Scalar nonlinear continuum damage models for ceramic matrix composites with significant in plane ply anisotropy
Abstract
Continuous fiber reinforced ceramic matrix composites (CMCs) are increasingly being employed in safety critical applications and the need the need for damage models to support the design, certification and sustainment has increased. In this work, we propose a simple but robust formulation for a 2D continuum damage model derived via a thermodynamics-based approach called openDM. Specifically, we consider a model with two scalar damage parameters that account for damage as a result of matrix cracking in the ply in both the fiber and transverse directions. The applicability of this model is considered for both a balanced 2D woven based SiC fiber reinforced composite and a 2D unidirectional ply based SiC fiber reinforced composite with predominately SiC matrices. While the response of the 2D woven composite was captured well with the two parameter model, the more anisotropic unidirectional ply based CMC was more difficult to capture unless a hybrid [0,90] ply was assumed in the model.
