Abstract

A unified numerical framework for progressive damage development at the laminate level in a polymer matrix composite (PMC) has been attempted by explicitly accounting for the damage progression at the micro-level. Coupling of macro- and micro- level has been accomplished with the help of non-linear homogenization principles wherein the effective degraded properties due to damage accumulated at the micro-level three-dimensional repeating unit cell (3D-RUC) is used as an input for the macro-level analysis. At the micro-level, matrix damage, fiber-matrix interface debonding and fiber failure have been explicitly modeled. The overall stiffness degradation due to these damage mechanisms have been considered while analyzing the PMC laminate at the macro-scale.
