3D boundary element analysis of creep continuum damage mechanics problems

In this paper, a boundary element formulation of creep damage problems for three-dimensional problems using isoparametric quadratic elements is presented. The Euler method with automatic time-step control scheme is implemented for time integrations. Creep rupture life is predicted using a continuum damage mechanics approach. The proposed formulation is applied to the FE Benchmark problems, uniaxial, perforated plate and Multi-material cross-weld problems.
