ABSTRACT = {A meshless method called reproducing kernel particle method (RKPM) is exploited to cope with elastic-plastic fracture mechanics (EPFM) problems. The idea of arithmetic progression is assumed to place particles within the refinement zone in the vicinity of the crack tip. A comparison between two conventional treatments, visibility and diffraction, to crack discontinuity is conducted. Also, a tracking to find the appropriate diffraction parameter is performed. To assess the suggestions made, two mode <i>I</i> numerical simulations, pure tension and pure bending tests, are executed. Results including <i>J</i> integral, crack mouth opening displacement (CMOD), and plastic zone size and shape are compared with finite element method (FEM).},
