Study of elastoplastic deformations in the dynamic interaction of two rigid deformable bodies

The article is a continuation of the study of dynamic dependencies between force and depth of introduction of conical indenters into barriers. The indenter is a cylinder with a pointed conical part. Indenters and barriers are made of steel. As a result of digitization of graphs of investigated dependencies, interpolation formulas of distribution of energies of elastic and plastic deformations in contact zone are obtained. Unlike the previous publication, which considered three variants of the angle of sharpening of the conical head part of the indenter, in this work the range of change of these angles is significantly increased. The obtained results can be used in the design of composite many rod punches and matrices for pressure treatment of sheet materials, as well as in the development of power and geometric parameters of impact tools for hydromolots.
