摘要

The mechanical behavior of ceramics in extreme environments can be qualitatively different from that observed at ambient conditions and at typical loading rates. For instance, during shock loading the fracture of ceramics is not controlled by the largest flaw. Computer simulations play an increasingly important role in understanding and predicting material behavior, in particular under conditions in which experiments might be challenging or expensive. Here, we review the strengths and limitations of simulation techniques that are most commonly used to model the mechanical behavior of ceramics. We discuss specific application areas of simulations, focusing on the effects of high strain rate, confined deformation volume, altered material chemistry, and high temperature. We conclude by providing examples of future opportunities for modeling studies in this field.
