Abstract This paper proposes a peridynamics-based statistical multiscale (PSM) framework to simulate the
macroscopic structure fracture with high efficiency. The heterogeneities of composites, including the shape,
spatial distribution and volume fraction of particles, are characterized within the representative volume
elements (RVEs), and their impact on structure failure are extracted as two types of peridynamic
parameters, namely, statistical critical stretch and equivalent micromodulus. At the microscale level, a bondbased peridynamic (BPD) model with energy-based micromodulus correction technique is introduced to
simulate the fracture in RVEs, and then the computational model of statistical critical stretch is established
through micromechanical analysis. Moreover, based on… More >
