The present paper describes a first-order analytic model of the breach of monolithic glass plate subject to impact by chunky projectiles. The purpose of the model is to provide a theoretical framework for examining the consequences of the impact breach experiments of Sun et al. [1]. A failure criterion of the Tuler-Butcher form [2] is used with the model. The experimental impact breach experiments joined with the analytic model demonstrate time-dependent failure and lack of replica scaling for the present data. Methods are explored for the assessment of fragmentation resulting from the impact breach of brittle materials.
