Abstract:In this paper, the finite element method is used to simulate the stable crack growth in three point bendtest pieces which are under the monotonic loading pattern. Both eight-node isoparametric elements and degenerate trian-gular elements have been incorporated in the programme. The results are compared with the experimental data.
Keywords:Crack Propagation   Elastoplastic deformation   Finite element mothod
