Predictive modelling of creep crack initiation and growth using Extended Finite Element Method (XFEM)

In this study, a numerical strategy for predictive modelling of creep in tension tests for the rectangular plate with a single crack and CT specimen based on the extended finite element method (XFEM) will be described in detail. A model of creep fracture initiation and creep crack growth (CCG) is...
