摘要

Two analytical mechanics-based models of dynamic fragmentation in brittle materials are pro- posed and solved to predict fragment size and time to fragmentation onset in terms of funda- mental material properties and the applied strain rate. Previous widely adopted analytical models of dynamic fragmentation are based on relatively simple energy balance arguments, and assume that the fragmentation event occurs instantaneously.
