Abstract
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. [Sun X, Khaleel MA, Davies RW. Modeling of stone-impact resistance of monolithic glass ply using continuum damage mechanics. Int J Damage Mech 2005;14:165–78]. A failure criterion of the Tuler–Butcher form [Tuler FR, Butcher BM. A criterion for the time dependence of fracture. Int J Fracture Mech 1968;4:431–7] 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.
