| Abstract: | A numerical mesomechanical model is presented based on the hypothesis of periodicity in composite mesostructure. A unified method for macroscopic and mesoscopic analysis of fiber reinforced composite structures is proposed by combining the mesomechanical model with the finite element method properly. In composite structure analysis the method can get the micro-stress and micro-strain in addition to the macro-stress and macro-strain. After being generalized, the method can be used to analyze composite structures with complex mesostructures and material non-linearity. |
