Abstract A rate-dependent peridynamic ceramic model, considering the brittle tensile response, compressive plastic
softening and strain-rate dependence, can accurately represent the dynamic response and crack propagation
of ceramic materials. However, it also considers the strain-rate dependence and damage accumulation caused
by compressive plastic softening during the compression stage, requiring more computational resources for the
bond force evaluation and damage evolution. Herein, the OpenMP parallel optimization of the rate-dependent
peridynamic ceramic model is investigated. Also, the modules that compute the interactions between material
points and update damage index are vectorized and parallelized. Moreover, the numerical examples are carried
out to simulate the… More >
