Dynamic solid particle damage in brittle materials: an appraisal

The damage caused by solid projectiles in the elastic and elastic /plastic target response regimes was characterized and analyzed. Projectiles of WC, nylon, and glass spheres impacted against a ZnS target. Semiempirical methods for establishing the relative importance of the target and properties on the impact damage were derived based on quasi-static indentation fracture characterization schemes and the quantification of the impact damage observations.
