Abstract: This paper focuses on the development of a multiscale progressive damage analysis framework for composite materials and structures based on the mechanics of structure genome (MSG). In the proposed approach, continuum damage mechanics is employed to model the damage evolution in the constituents at the microscale. The damage model features separate damage variables for matrix and fiber in tension and compression to capture the distinct failure mechanisms. Mesh objectivity is achieved using the crack band model. The MSG-based multiscale methodology provides an efficient way to link the microscale damage behavior with the structural level response. The effectiveness of the developed approach is demonstrated through several numerical examples, including the strength prediction of unnotched and notched unidirectional fiber reinforced composite laminates. The results show good agreement with experimental data. This multiscale damage analysis framework provides an accurate and efficient tool for progressive failure analysis and strength prediction of composite structures.
