چکیده مقاله:

In this work, using numerical methods (FEM & XFEM) for optimize local static force position in three-dimensional solid with semi-circle crack at mid front surface. Crack is modeled in finite element with 3D interaction integral (M-integral) and displacement correlation methods for analysis fracture parameters. XFEM method enrich element with strong discontinuity (crack tip) for analysis three dimensional mixed-mode stress intensity factor parameters. Compare fracture parameters conclusion with FEM and XFEM methods
