Mathematical modelling of longitudinal elastic central blow of non-uniform rod system about a rigid barrier is carried out, at not keeping communications by the analytical decision of the wave differential equation by a method of Dalambera. The rod system consists of a homogeneous core of constant cross-section section and the step non-uniform core having two homogeneous sites of various length and the area of cross-section sections. Ties with a rigid barrier and between cores are not witholding.
Keywords: blow, deformation, mathematical modelling, speed.
