| Popis: | Different analytical formulations are reported in recent works to model the failure strength and the progressive failure of different fiber metal laminates (FMLs). Although the basis for all these formulations is classical lamination theory (CLT), the models differ with each other while modeling the stiffness degradation. A common analytical formulation that is independent of configuration of the laminate will be very helpful for the designers in this field. Present work is aimed to develop such a model with the help of a hybrid degradation scheme, which uses constant degradation factors based on the condition of the adjacent lamina. This hybrid degradation scheme has helped to model the occurrence of multiple failures inside a lamina during failure progression. The formulation is tested with three types of FMLs and the results show that the formulation is very much helpful in predicting the failure strength and progressive failure. |
