An approach to determining the parameters of kinetic strength theory based dynamic model of brittle solids mechanical behavior

Earlier the authors developed a discrete element based numerical model of dynamic mechanical behavior of brittle materials. The model is based on the concept of kinetic theory of strength. An important problem in the application of the proposed model to the study of features of dynamic response of real materials is lack of information about the dependence of model parameters on stress relaxation times (including time of fracture development). The present paper proposes an analytical approach to determining these dependencies for different brittle materials.
