In this work, EFG method has been applied to solve elasto-plastic fracture mechanics problems. This method, which belongs to the class of meshless method, facilitated the modeling of any arbitrary crack with an ease. To carry out this work, the incremental relations for plastic deformation of a system are used, and non linear equations have been obtained using incremental theory of plasticity. These equations are solved by assuming piece wise linear approximation in each of the load step. The size of plastic zone has been calculated around the tip of the crack by elasto-plastic EFG method.
