This article illuminates some general features and provides elementary
interpretations of the deformation, damage, and failure of brittle solids characterized
by very low fracture energy. The dynamic response of these materials is determined
to a large extent by stochastic and random factors. The investigation emphasis is on
the moderate-to-extremely high rate range (10 s 1, 1 109 s 1), explored under practically
identical in-plane stress conditions. The statistical approach is based on
repeated particle dynamics simulations for different physical realizations of micromechanical
disorder of a 2D brittle discrete system. The proposed strategy is computationally
intensive, which necessitates simplicity of the laws governing the
interparticular interaction. Based on the simulation results, an expression is proposed
to model the mean tensile strength dependence on the strain rate. The linearity
of the rate dependence of the stress-peak macroscopic response parameters is
observe...d and discussed.
