Influence of the Laser Welding Direction of Thin DP600 and the Residual Stresses Relaxation Obtained by Simulation and Neutron Diffraction

MR Liu, A Kouadri-Henni, B Malard - Key Engineering Materials, 2022 - Trans Tech Publ
Laser-welded structures are often subjected to dynamic service loads ranging from cyclic
fluctuations to completely random ones. The laser-welded lap joints suffer from defects …

[PDF][PDF] Simulation of low-cycle fatigue residual stress in DP600 steel laser-welded structure

M Liu, A Kouadri-Henni, B Malard - ICRS 11-The 11th …, 2022 - researchgate.net
With the Abaqus finite element method, the residual stress of DP600 steel after laser welding
and low-cycle fatigue is simulated. Due to the large temperature gradient during laser …
