Lennart Josefson
Lennart Josefson is a full professor emeritus in Solid Mechanics at the Division of Material and Computational Mechanics. His main research areas are computational welding mechanics and fatigue of welded structures. He has been a member of technical committees within the International Ship and Offshore Structures Congress (ISSC) for some 30 years, and he was the chairman for the Materials and Fabrication Technology Committe for the period 2015 - 2022. Lennart was also the chairman for the Swedish Welding Commission's working group on Rail Welding for the period 2003 - 2023. He is currently a principal reviewer for the Journal Welding in the World. Lennart still teaches Mechanics and Thermodynamics for the foundation year and fatigue of welded structures at the Master's level.
