Dean Dang et al. Fusion welding process is widely used in shipbuilding and automobile industries to join thin plate panel structure. High tensile strength steel thin plate used instead of low carbon steel to reduce the weight. In thin plate buckling distortion is occurs and it loss the structural integrity and dimensional accuracy. In this study, welding distortion in a large thin plate panel structure was predicted by means of elastic FEM based on inherent strain theory and interface element formulation. In this concept of inherent strain and inherent deformation mentioned. In this elastic strain, plastic strain, thermal strain, creep strain.
Simulation cases study four simulation case
A).Double- sided welding procedure large deformation theory.
B).Double -sided welding procedure small deformation theory.
C).Single-sided welding procedure large deformation theory
D).Single-sided welding procedure small deformation theory. Simulation Result suggest that welding procedure has a certain influence on the final welding distortion. Double sided welding procedure can produce a lager tendon force so it can increase the buckling property especially in thin plate structure. Based on the simulation result, we have known that the assembly sequence has a significant influence on the final distortion.
