Description
| - Brittle-matrix composites (BMC) loaded in tension exhibit strain hardening behavior. A number of simplified analytical models have been developed in the past to effectively capture the fragmentation process of BMC starting from the elastic range, over the gradual evolution of matrix cracks up to the point of the saturated crack density and/or the failure of the weakest crack bridge. In the present paper the model formulation is decomposed into two parts: On the microscopic scale the debonding problem is solved a-priori for a single representative crack bridge including local effects in the material structure (short fiber orientation, irregular penetration by the matrix into a multifilament yarn structure, etc.). The crack-bridge model delivers a load dependent profile of the strain transferred between the reinforcement and the matrix that is further included in the fragmentation model of the composite. The mesoscopic simulation of the fragmentation process includes a numerical integration which evalua
