Anisotropic Damage of Fiber-Reinforced MMC Using Overall Damage Analysis
Publication: Journal of Engineering Mechanics
Volume 121, Issue 11
Abstract
An anisotropic damage model is proposed for fibrous metal matrix composites (MMC) with a ductile matrix. The model incorporates damage mechanics with micromechanical behavior. An overall damage tensor, M for the whole composite is used in this analysis. This formulation allows the proposed damage model to directly use the elastoplastic stiffness tensor obtained for the undamaged effective configuration. An explicit expression is obtained for the elastoplastic stiffness tensor for the damaged composite material. Numerical solutions are obtained for different types of laminate layups compared with experimental results.
