A computational multiscale model for anisotropic failure of sheet molding compound composites

We present a holistic multiscale approach for constructing anisotropic criteria describing the macroscopic failure of sheet molding compound composites based on full-field simulations microscale damage evolution. use an model that directly operates compliance tensor, captures matrix and bundle via dedicated stress-based allows comparison simulation experimental results. To identify material-parameters used in non-linear time-consuming simulations, we utilize Bayesian optimization with Gaussian processes. validate predictions subsequently distributions taken from findings. propose surfaces stress space stiffness-reduction triggered to cover both structural analysis design process perspective.
