Paper Title:
Effect of Weld Metal Hardening Property on Deformation Behavior and Crack Driving Force of Mismatched Welded Joint
  Abstract

Effect of weld metal hardening property on the deformation behavior and crack driving force of strength mismatched welded joint with crack has been investigated using finite element method under plain strain condition. The results show that when the apply load is small, there is only small scale deformation around the crack tip, the whole structure is still in linear or small scale yielding condition therefore the weld metal hardening property has no significant effect on crack driving force. As the applied load increasing, the deformation region enlarges and at the same time the deformation level around the crack tip deepens, the increasing of weld metal hardening property decreases the local deformation level, consequently leading to the decreasing of the crack cracking force.
