%X Penalty method is used to satisfy essential boundary conditions for meshless method, and the penalty parameters are studied for the selection. The stress field of elasticity including single crack is analyzed and the effect of integral contour on computed efforts of stress intensity factors is discussed. Numerical examples show that the present implementation effectively computes stress concentrations and stress intensity factors at cracks, and crack propagation can be accurately modeled.
