Per Lindström Lussi

Per Lindström Lussi is a Research Professor specializing in welding mechanics and structural integrity at Linnaeus University's Faculty of Technology, Department of Mechanical Engineering. With a doctoral degree in Computational Welding Mechanics from University West (2015), he focuses on Fatigue and Fracture Avoidance (FFA) and Fitness For Service (FFS) in marine and offshore structures.

Education:

• Doctoral Thesis in Computational Welding Mechanics (2015), University West
• Licentiate of Naval Architecture and Ocean Engineering (2005), Chalmers University
• Master of Science in Marine Engineering (2001), Chalmers University
• Diploma of Commercial Management & Organization in Nautical Science (1999), Chalmers University
• Bachelor of Science in Marine Engineering (1991), Kalmar Maritime Academy
• International Welding Engineer certificate (2001), IIW

Dr. Lindström Lussi's research focuses on welding mechanics, residual stress analysis, and structural integrity assessment of marine and offshore structures. His work bridges theoretical computational models with practical engineering applications, particularly in fatigue and fracture mechanics. He has extensive experience in both academic research and industrial applications, having worked with major organizations including Lloyd's Register, DNV GL, and Westinghouse Electric.

His recent publications demonstrate a strong focus on computational welding mechanics, with particular emphasis on residual stress prediction, fracture mechanics, and additive manufacturing applications in marine contexts. The research shows progression from fundamental welding process modeling to advanced applications in structural integrity assessment and seaworthiness analysis.

Professional Affiliations:

• Swedish delegate in IIW Working Unit C-X "Structural performances of welded joint - Fracture avoidance" (since 2006)
• Committee member, International Ship and Offshore Structures Congress (ISSC)

Dr. Lindström Lussi leads research in the Welding Mechanics Laboratory and is active in the Smart Industry Group. His current projects include seaworthiness assessment of WAAM-manufactured marine propellers, FEA of residual stresses in welded structures, and investigation of NORM contamination in LNG fuel systems.
