To the memory of Fred Nilsson

holm, has died at the age of 62.

In 1969, Fred joined the research group of Janne Carlsson at KTH. Four years later, he received

his DSc with a groundbreaking dissertation on dynamic crack propagation. He was to become one

of the world’s most influential researchers in this area.

After a year at Carbox, Ystad, where he developed methods for the design of heavy plate-

forming equipment, Fred was back at KTH to produce some of his finest research in fracture me-

chanics. In the early 80’s, he worked at IFM Akustikbyrån and the Swedish Nuclear Power Inspec-

torate, where he developed novel methods for the assessment of the reliability of reactor pressure

vessels. After four years as a Professor of Solid Mechanics at the University of Uppsala, Fred re-

turned to KTH, where he was appointed Professor of Solid Mechanics in 1991 – the circle was

closed.

More recently, Fred gave impetus to fatigue research, e.g., comprehensive investigations on

crack closure and fatigue-crack growth. During his years as a member of the board of the Swedish

Fatigue Network (UTMIS), Fred and KTH played a very active role, thus increasing the importance

of the organisation to Swedish industry.

Wherever he got involved, Fred quickly became a driving force. His critical but always con-

structive attitude enhanced the level of the scientific dialogue. We, who have been his colleagues

and friends, will always keep Fred in grateful memory.
