INFLUENCE OF BI-MATERIAL INTERFACE ON CRACK PROPAGATION DIRECTION IN MULTILAYER COMPOSITE


Abstract eng:
A substantial number of experimentally based works indicate the changes in crack propagation direction on bi-material interface in composite laminate materials. The paper is focused on prediction of crack propagation direction after its passage through the interface between two materials. Stress components in the vicinity of crack tip were investigated by a numerical simulation. For determination of the consequent propagation direction the minimal strain energy density criterion was employed. More accurate results were obtained by means of jointed numerical and analytical solution. The values of crack propagation directions obtained for layered composite were compared with experimental data.
