Behavior of Brittle Materials Under Dynamic Loading

Abstract

Dynamic loading of brittle materials is related to many applications, including explosive excavation of rocks, design of ceramic armor, meteor impact on spacecraft windows, particle damage to turbine blades, etc. When brittle materials are exposed to impact or explosive loading, inelastic deformation, fracture, and fragmentation occur under conditions of three-dimensional stress, where at least one stress component is compressive. Unlike fracture and fragmentation of brittle materials under tensile loading, response to compression is far from understood. Rapid application of loads can also introduce rate dependencies which make the analysis even more complicated. This review report is mainly focused on compressive failure. We have collected, reviewed, and assessed information on the behavior and properties of brittle materials that are of greatest current interest, namely polycrystalline ceramics, glasses, and rocks.
