Micro Abstract:
We present a two-scale anisotropic damage model that captures matrix damage and fiber-matrix interface debonding. Based on the fiber orientation distribution and a Weibull probability distribution of the interface strength, the damage evolution on the microscale is determined. Within this work focus lies on the comparison of different matrix damage evolution models. To predict the macroscopic behavior, a mean field homogenization with the Mori-Tanaka method based on orientation tensors of second and fourth order is applied.
