TC10 UPDATE 2012

On 3rd of October 2011 a Meeting of ESIS TC10 on Environmentally Assisted Cracking (EAC) and of the Subcommittee on Hydrogen Degradation was held at Lviv National Technical University (Ukraine) in conjunction with the Second Ukrainian-Greek Symposium on Fracture Mechanics of Materials and Structures from 3rd to 7th of October.
The TC 10 Chairman, Prof. Jesus Toribio, University of Salamanca, Spain, opened the meeting which comprised the following presentations:
  • 20 Years ESIS TC10 on Environmentally-Assisted Cracking - what was achieved, what remains to be done? (Dr. W. Dietzel, Helmholtz-Zentrum Geesthacht, Germany).
  • State of a realization of the Agreement on Cooperation between the National Academy of Sciences of Ukraine (NASU) and ESIS and the activity of Ukrainian-Polish-German Summer Schools on Fracture Mechanics (Prof. H.M. Nykyforchyn, Karpenko Physico-Mechanical Institute of the NASU, Lviv).
  • The future activities of ESIS TC10 “EAC" and of the Subcommittee on "Hydrogen Degradation" (Profs. J. Toribio and H.M. Nykyforchyn).
Dr. W. Dietzel talked about the history of the TC, which was launched in April 1990 with a first Workshop on "Environmentally Assisted Cracking" which had been initiated by the GKSS Research Centre in Geesthacht, Germany, and was followed on by the foundation of the Sub-committee on “Hydrogen Degradation” in 1995, following an initiative by the members of the Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine (KPMI). Dr. Dietzel reminded the audience that the main objective of ESIS TC10 was - and continues to be - a merge of research experience in the areas of fracture mechanics and of environmental degradation/corrosion of materials. From the very beginning, the work of TC10 and of its Sub-Committee was focused on the development of innovative methods for testing of SCC, on the elaboration of guidelines for controlling SCC, supported by the European Commission, and on organising very successful and fruitful workshops devoted to problems of EAC and on supporting and co-sponsoring EAC related conferences. In addition to these tasks, in future the participation in existing networks such as technical associations and Working Parties and the formation of new networks should play an important role in the work of the TC.

Prof. H.M. Nykyforchyn informed about the state of realization of the Agreement on Cooperation between the NASU and ESIS, which was signed in Kyiv on October 26, 2009 by the ESIS President (2006-2010), Prof. E. Gdoutos, and the NASU President, Prof. B.E. Paton. The Program of scientific and technical cooperation for the years 2009-2014 includes several items, the main is the organisation of Ukrainian-Greek Symposia on Fracture Mechanics of Materials and Structures (FMMS). The first such Symposium was organised in Xanthi, Greece, October 20-23, 2010, with a strong focus on hydrogen degradation from the Ukrainian side. Ten speakers from Ukraine participated in the Symposium where the Greek side covered the costs of accommodation and living for the Ukrainian colleagues. The 2nd FMMS was organized in Ukraine at the same conditions for the Greek participants. 

Special attention was paid to the recently hold 12th Polish-Ukrainian-German Summer School (SS) on Fracture Mechanics, which was held from 18th to 23rd September, 2011, at Warsaw University of Technology, Poland) in conjunction with the Symposium “Mechanical Properties of Nanomaterials – Experiments and Modelling” of EMRS Fall Meeting 2011. This SS has ESIS status in Central and Eastern Europe following a decision of the ESIS Council on 12th September, 2002, in Cracow, Poland. 39 participants, including 21 from Poland, 14 from Ukraine, three from Austria and one from Germany were present. Further, the Symposium was open to the participants of the SS who presented recent achievements in deformation and fracture of nanomaterials. During the meeting it was tentatively agreed that the next, i.e. the 13th SS will be held in 2013 and will be hosted by the Wroclaw University of Technology, Poland. More information about the SS 2011 can be found in the note “The 12th Polish-Ukrainian-German summer school on fracture mechanics and strength of materials”, published in the Journal “Physicochemical Mechanics of Fracture”, 2011, no 5, pp. 130-132.

Prof. J. Toribio imparted to the participants of the Lviv meeting potential future activities of TC10. Main tasks for 2012 would be to organise one or more special session(s) on EAC during ECF19 in Kazan and for 2013 to organise a workshop on EAC problems. As possible places for this workshop, Porto Marghera/Venice, Italy, and Salamanca, Spain, were considered.

TC10 UPDATE 2010

20 Years ESIS TC10 on Environmentally-Assisted Cracking
 
Following a Kick-Off Workshop at GKSS in 1990 related to the topic of "Environmentally Assisted Cracking", EAC, the group was formally established as ESIS TC 10 in 1991. The main objective of TC10 was to merge research experience in the areas of fracture mechanics as a method of failure assessment, and of environmental degradation/corrosion of materials. The work has always been strongly related to the development of fracture mechanics test and evaluation techniques and their application to problems of EAC, with main emphasis on monotonic loading (i.e., stress corrosion cracking). In 1995, a Sub-committee on “Hydrogen Degradation” was founded following an initiative of members of the Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine.
 
Since then, TC 10 and its Sub-committee have jointly organised a number of successful technical meetings and workshops with contributions typically addressing materials properties under environmental degradation; inspection and control; risk assessment; damage mechanisms and their prevention; corrosion management.
 
In the past, the work of TC 10 was focused on the development of innovative methods for testing of EAC and on the elaboration of fracture control guidelines for controlling EAC. The work was supported by the European Commission through the grant of two research projects which involved more than 30 European laboratories and research groups and lead to the introduction of a new ISO standard on accelerated EAC testing.
 
Now, TC 10 takes up new EAC related tasks for which the open and versatile structure of the group appears ideally suited. Knowledge Management in the area of environmental degradation of metallic materials and the solution of complex technical problems are new challenges, and the participation in existing networks such as technical associations and Working Parties (Communities of Practice) and the formation of new networks will play an important role in future. One example is the “Mediterranean Network on Corrosion and Integrity” initiated by TC10 and aimed at connecting scientists and engineers with expertise in corrosion, environmentally assisted cracking and material science to support industry needs in the Mediterranean countries.
 
Apart from this, TC10 continued to support and co-sponsor EAC related conferences and workshops. The most recent were the
  • 4th International Conference "Fracture Mechanics of Materials and Structural Integrity", 23 -27 June 2009, Lviv, Ukraine, in combination with the
  • 11th Polish-Ukrainian-German Summer School on Fracture Mechanics, 23 - 27 June 2009, in Lviv, Ukraine,
  • 12th Quadrennial International Conference on Fracture, ICF12, July 12-17, 2009, in Ottawa, Canada - Conference "WEAR PROCESSES 2009", 19-20 November 2009 in Szczecin-Świnoujście, Poland.
TC10 was also strongly involved in the Workshop "Integrity of Pipelines Transporting Hydrocarbons" which was organized in the frame of NATO “Science for Peace” in Biskra, Algeria, April 26-29 2010.
 
For the forthcoming 18th European Conference on Fracture TC10 has organised a Symposium on "Environmentally Enhanced Effects" comprising a total of six sessions, and will hold a technical meeting in conjunction with this symposium. 


TC10 UPDATE 2009

At the 17th European Conference of Fracture, ECF17, TC10 and its SubCommittee on "Hydrogen Degradation" organised in close collaboration with the Chairmen of this conference three sessions on "Corrosion and SCC, Hydrogen Embrittlement" comprising 12 presentations.
 
On 6-7 October 2008, TC10 held a Workshop on “Social Networks for Corrosion and Life Prediction of Industrial Components” in Porto Marghera (Venice), Italy, in which also corrosion experts from North Africa participated. One of the objectives was to create an ESIS TC10 / Mediterranean Network on corrosion/EAC problems.
 
TC10 and its SC are involved in organising the 4th International Conference "Fracture Mechanics of Materials and Structural Integrity" which will take place from 23 - 27 June 2009 in Lviv, Ukraine. For the 12 th International Conference on Fracture, ICF12, taking place from 12 - 17 July 2009 in Ottawa, Canada, TC10 organised together with other experts special sessions on the topics of "Corrosion, Environmentally Assisted Cracking and Corrosion Fatigue" and "Hydrogen Embrittlement".
 
TC10 and its SC support the organisation of the Conference "Wear Processes 2009" to be held from 19 - 20 November 2009 in SzczecinŚwinoujście, Poland.

TC10 UPDATE 2008

The 10th Polish-Ukrainian-German Summer School on Fracture Mechanics, “Fracture Mechanics and Strength of Materials in Hydrogen”, organized by the Wroclaw University of Technology, the Karpenko Physico-Mechanical Institute of National Academy of Sciences of Ukraine and the Technical University of Dresden, was held on 10-14 June 2007 in Trzebieszowice, Poland. The Summer School had about 70 participants, and the programme was elaborated in close collaboration with ESIS TC10, its SC on "Hydrogen Degradation", and ESIS TC13 "Education and Training". Following an ESIS Council decision made at ECF 14 in Cracow, these schools have obtained the status of ESIS Summer Schools in Central and Eastern Europe. For more information see Link "Minutes of the esis TC10 and TC13" under "TC10 UPDATE 2007" at the TC 10 web page.

For the 17th European Conference of Fracture, ECF17, TC 10 and its SC have organized in close collaboration with the Chairmen of this conference a special section of the ECF17 program. This section will comprise a session on "General Aspects of Environmentally Assisted Cracking" as well as one on "Hydrogen Degradation".

FUTURE ACTIVITIES
For October 2008, TC10 plans to organize a Workshop on “Corrosion/SCC Problems in Industry” in Porto Marghera (Venice), Italy. Special emphasis will be on “Case histories and their management”. In addition to the TC 10 members and all interested participants from ESIS member states corrosion experts from North Africa will be invited in order to foster an ESIS TC10 / Mediterranean Network on corrosion/EAC problems.

TC10 is further involved in the organization of the next International Conference on Fracture, ICF12, in Ottawa, Canada, in 2009. Together with other experts, special sessions will be organized comprising the topics of "Corrosion, Environmentally Assisted Cracking and Corrosion Fatigue" and of "Hydrogen Embrittlement".


TC10 UPDATE 2007

1.Activity

For the 16th European Conference of Fracture, ECF16, the TC and its SC jointly organized a Special Symposium on Environment Assisted Fracture. The aim of this symposium was to bring together researchers involved in experimental and theoretical investigations of this failure phenomenon and to present talks that would address the state-of-the-art in the current understanding of corrosion and corrosion assisted cracking. The symposium comprised a full day session involving 18 contributions, and successfully fostered discussions on all aspects of environmentally assisted damage, degradation, and rupture processes. More contributions related to environmentally assisted cracking (EAC) problems were presented in a separate Track and in some of the Special Sessions.

In December, Dr. Giovanna Gabetta, co-chair of ESIS TC 10, took part in the 25th Annual Conference “Corrosion Problems in Industry”, the silver Jubilee of Egyptian Corrosion Society (ECS), in Palmera Hotel, El Soukhna, Egypt. The conference saw a significant number of presentations in the field of corrosion, including presentations dealing with EAC problems, like failure analysis, SCC testing, and integrity of pipelines.  On the occasion of this conference, it was discussed to start a cooperation network between ESIS TC 10 and the Egyptian Corrosion Society, which could be a bridge toward the corrosion experts in the North African area. As a first step, an ad-hoc group was established (participants: Layla A.Al-Juhaiman, Rabab M.El-Sherif, Giovanna Gabetta) with the aim of collecting case histories for a data base.

2. Future actions
TC10 is now planning to organize a meeting on “Knowledge management for EAC problems” with potential emphasis on “Case histories and their management”. For this meeting, which is likely to be held in Fall 2007 in Italy, participants from the Mediterranean area will be invited in addition to the TC 10 members, so that it is likely to become the first meeting of a future ESIS TC10 / Mediterranean Network on corrosion/EAC problems.


TC10 UPDATE 2006

ACTIVITIES
No formal meetings of the TC were held in 2005. However, the TC10 has been involved in a number of activities:

  1. The successful submission of a proposal for a new research project to the Science and Technology Centre of the Ukraine (STCU) which had been prepared by the Institute of Applied Problems of Mathematics and Mechanics (IAPMM) and the Karpenko Physico-Mechanical Institute (KPMI), both of the National Academy of Sciences of the Ukraine. The project entitled "Monitoring, Technical Diagnostics and Remaining Life Prediction for the Oil Transit Systems" is related to the long-term service of oil and gas pipelines and will address the problems arising from a loss of workability, the existence of cracks, and the degradation of the mechanical properties of the steels used for these pipeline systems.
    The project includes the development and application of appropriate technical monitoring and diagnostics tools to assess the technical state of pipelines and other oil transportation equipment by detecting corrosion-mechanical damages at an early stage, and evaluating possible changes in the mechanical properties of the materials involved which lead to material degradation. It will also comprise the development of suitable methods for the prediction of residual lifetimes of oil transportation systems and the establishment of new criteria for the workability of pipelines and related equipment, and their application to existing structures. As an additional outcome of the project, appropriate modifications to existing normative documents pertaining to the strength, durability, and reliability analysis of existing pipeline systems for oil transportation are expected.
    The project is closely linked to the objectives of ESIS TC 10 and will hence be actively supported by members of the TC.

  2. According to the strategy discussed at the last TC10 Workshop (October 2004) on "EAC in High Strength (Pipeline) Steels", the TC has established links to the European Pressure Research Group, EPRG, on the occasion of a Research Fund Coal and Steel (RFCS/ECSC) dissemination forum on "X100 Steel Pipe for High Pressure Gas Transportation" held at the Salzgitter Mannesmann Forschung in Duisburg in April 2005.

CALENDAR 2006 At the 16th European Conference of Fracture, ECF16, to be held on July 3-7, 2006, in Alexandroupolis, Greece, TC10 has organised a Special Symposium on Environment Assisted Fracture. The symposium will have about 20 presentations and is scheduled for Tuesday, 4 July; Linked to this symposium, a technical meeting of TC10 will be held.

Prof. Nykyforchyn celebrated his 60th birthday. The ESIS TC10 wants to honour him with the following poster:
