In this paper, firstly the elasto-plastic finite element analyses of a center cracked plate are performed based on deformation and incremental plasticity theory to investigate the difference between solutions obtained through both theory and some factors determining the path independence of J-integral, and loading condition go an element in the vicinity of crack tip are examined. Secondly, the analysis of a longitudinal bead-welded joint with a center crack is conducted based on incremental theory to discuss the path independence of J-integral and loading condition of elements on phase boundary.
