【 摘 要 】

AISI 1018 low carbon steels are widely used in dynamic environment where material undergo sudden loads. In this study the Finite element simulation of impact test of Spin arc welded 1018 steel plates was analysed using Abaqus Explicit 6.14. Damage evaluation of spin arc weld and base metal are proposed by Johnson-Cook failure criterion model. The geometry, material and contact properties of base and weld metal are obtained from tensile test results. The specimen and striker are controlled by linear surface to surface interface. The numerical results are compared with experimental Charpy impact test for validation.
