Dynamic Response of a Cylindrical Cavity of Finite Length in a Bilinear Material.

Abstract

The response of a cylindrical cavity of finite length in a bilinear (hysteretic), layered, material is obtained for a pressure pulse, p(tau), applied to the inner boundary of the cavity. The problem is two-dimensional in r, z coordinates, the loading being axisymmetric. The solution is obtained from a characteristic approach combined with the method of fractional steps. Results are presented for a non-layered configuration, and also for a case in which three layers are present. Comparisons of these solutions with results from a finite difference code using the same two-dimensional configurations are given. Further development will allow for the presence of a structure lining the cavity in a bilinear material.
