Abstract
A stochastic model for crack propagation in random heterogeneous media uses mesoscopic representations of elastic and fracture properties. Monte-Carlo simulations with a phase-field approach assess subscale randomness effects. Mesoscopic descriptors and random elasticity tensors are introduced for scale transitions. Fracture toughness is identified via an inverse problem. A non-Gaussian stochastic model predicts the macroscopic response, accurately matching full-scale simulations.
