Abstract
This contribution aim is to develop the extended prediction of numerical simulation for crack ductile fracture behaviours. The Rousselier’s damage model is chosen to describe the damage mechanism by implementing their constitutive law into UMAT subroutine code. In order to enhance the development of crack growth, the Extended Finite Element Method (XFEM) is used, which has a capability to calculate the discontinuity element without need any remeshing purpose. This study is discussed in the context of finite element results of a symmetrically single-notched and CTS specimen, which will be verified with experimental data. As a result, these were found to be good correlation in terms of stress-strain curve, the crack path and also load-displacement accuracy. Therefore, from this experience, it is demonstrated that the capability of XFEM linked with Rousselier’s model for resulting numerical formulation in structural damage benchmark problems.
