A high gradient zone (HGZ) comes into existence in both rotation and deflection displacement fields in the vicinity of a yield line in a plate structure with elasto-plastic material. This HGZ makes the displacements non-smooth locally around the yield line. The Extended Finite Element Method (XFE...
