Stressed state of a hollow two-layer cylinder under dynamic loads

The dynamic problem of an elastic two-layer hollow cylinder whose surfaces are loaded by arbitrary forces is solved by the method based on the use of finite differences solely with respect to time. The numerical calculations of the stress concentration on the inner and outer surfaces and the surface of conjugation as functions of times are carried out for cylinders with different thicknesses of the layers under impact loads. The dependences of stresses on the radial variable r and time parameter τ are illustrated for two-layer cylinders subjected to impacts on the inner and outer surfaces.
