Effect of Strength Mis--matching on Elastic--plastic Deformation Behaviors of Welded Joints with Cracks
摘要
Abstract
Elastic--plastic deformation behaviors of strength mis--matched welded joints with cracks were investigated using finite element method. Effects of strength mis--matching, hardening property of weld metal and crack length on plastic deformation were analyzed. The results show that strength mis--matching has significant influence on plastic deformation of welded joint. Deformation is first concentrated in weld for under-- matched joint, while for over-- matched joint, strength over-- matching can protect weld metal to some extent. When strength mis--matching facor is constant, the plastic deformation trends for welded joints with different hardening properties of weld metals are similar,whereas local plastic deformation levels are different. Plastic deformation increases with the hardening property of weld metal decreasing.关键词
