A Study of Elastic-Plastic Boundary Propagation in a Tube of Elastic-Perfectly Plastic Material Under Dynamic Loadings of Different Types

Аннотация

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 loading a tube is examined.
