In engineering practice, dynamic processes are crucial. Therefore, modeling and research of these processes are urgent tasks. To study the shock processes, a mechanorheological visco-elasto-plastic model was developed. An important parameter of the model is a force corresponding to the occurrence of plastic deformations. An improved algorithm and a new computer program for studying impact processes using the visco-elasto-plastic model with adjustable elastic-plastic transformations were developed. Differential model motion equations were built. The conditions of transformations were studied for the transition from elastic to plastic deformations, from the loading stage to the unloading one. Functions of the model were described, an algorithm of the model was developed and described.
