NUMERICAL INVESTIGATION OF CRACK GROWTH IN METALS AND COMPOSITES

This work presents the simulation study of fracture behavior of steel and composites. The crack growth behavior of the material is simulated by extended finite element method (XFEM). XFEM allows the modeling of arbitrary geometric features independently of the finite element mesh. The crack surface...
