Witryna24 lut 2016 · In order to simulate the crack propagation under compressive loading, the maximum tangential stress (MTS) criterion was firstly improved and incorporated in developed extended finite element method (XFEM) code. The XFEM allows crack growing through the finite element mesh without re-meshing process.
