Timo Björk

Timo Björk is a Professor at the LUT School of Energy Systems, Lappeenranta University of Technology. His primary research focuses on fatigue analysis of welded joints, high-strength steels, additive manufacturing, and structural integrity. Key areas of expertise include the evaluation of fatigue performance under variable loading conditions, advanced welding techniques, and computational methods like the 4R approach and finite element analysis.

His work involves experimental investigations of material behavior, including studies on ultra-high-strength steels (e.g., S700K, S960MC, S1100), aluminum alloys, and stainless steels. He explores methods to enhance joint fatigue life through treatments such as high-frequency mechanical impact (HFMI) and post-weld treatments. Recent projects address challenges in additive manufacturing for industrial applications, laser powder bed fusion, and the integration of computational models with physical testing.

Björk collaborates on topics like distortion control in welding, material characterization under elevated temperatures, and fracture mechanics. His contributions span structural engineering, marine applications, and automotive steel components. He has published extensively on fatigue assessment methodologies, joint design optimization, and the mechanical properties of novel materials processed via advanced manufacturing techniques.
