Elastic-Plastic Boundaries in Plane and Cylindrical Wave Propagation of Combined Stresses

摘要

A general study is given of plane and cylindrical wave propagation of combined stresses in an elastic-plastic medium. The coefficients of the governing differential equations, when written in matrix notation, are symmetric matrices and can be divided into sub-matrices each of which has a special form. The relations between the stresses on both sides of an elastic-plastic boundary are derived. Also presented are the restrictions on the speed of an elastic-plastic boundary. (Author)
