Abstract: The fracture simulation of random particle reinforced composite structures remains a challenge. Current techniques either assumed a homogeneous model, ignoring the microstructure characteristics of composite structures, or considered a micro-mechanical model, involving intractable computational costs. In this talk, we will introduce a peridynamics-based statistical multiscale framework to simulate the macroscopic structure fracture with high efficiency. A key point of the approach is that the scale separation-based statistical multiscale strategy is used to define a macroscale BPD model with an equivalent micromodulus and a statistical critical stretch that are evaluated based on microscale representative volume elements. Consequently, the proposed method can take into account the microstructural characteristics of composites when performing macroscopic fracture analysis, and at the same time save the computational cost.
