A STUDY OF ELASTIC-PLASTIC BOUNDARY PROPAGATION IN A TUBE OF ELASTIC-PERFECTLY PLASTIC MATERIAL UNDER DYNAMIC LOADINGS OF DIFFERENT TYPES

摘要

The dynamics of distribution of the border between areas of elasticity and plasticity for a hollow thick-walled cylinder under the influence of the internal pressure applied instantly is investigated in this work. Proof of the accuracy of the obtained numerical solution is provided. A more general regime of loading a tube is examined.
