Witryna10 kwi 2015 · The XFEM was initially proposed to tackle the strong-discontinuity problem in relation to crack growth and was soon extended to other problems characterized by localization, complex geometries and multi-phase. The method has two main advantages over other numerical methods. 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.
