Dynamic Response of an Axisymmetric Lined Cylindrical Cavity of Finite Length in a Bilinear Material.
Abstract
A pressure pulse p(theta) is applied to the interior of an axisymmetric, lined cylindrical cavity of finite length, embedded in a bilinear type dissipative material. The cavity lining is a structure composed of a thin, axisymmetric cylindrical shell with bending stiffness, welded to a flat circular plate at the bottom. The response of the structure is found from a variational procedure on the energy expressions in finite difference form. The response of the dissipative material is found from a pseudo-characteristic scheme combined with a fractional step method (and given the name PC scheme). Results are presented and compared with results from a finite element scheme applied to the same configuration. These comparisons illustrate the use of this PC scheme code as a check solution for a large computer code such as the finite element one.
