One of the possible explosive transformation initiation mechanisms under low-velocity impacts is considered. It is based on the surface explosive heating caused by rubbing against the surrounding materials. The implementation of kinetics equations within D technique is presented. The algorithm of accounting for the forces of friction occurring on the interfaces during the interaction of an explosive with the surrounding materials is described. The paper gives results of the numerical simulation with the described kinetics for experiments of the Stiven Test type. Keywords: D technique, low-velocity impacts, Stiven Test, friction coefficient, initiation of explosive transformations.
