Transient Response of a Metallic Capsule to an Internal Pressure Pulse

Abstract

Response of a metallic capsule to a transient internal pressure is analyzed adopting two models. The first is a two-dimensional (2-D) model with finite extent in the plane of the capsule's cross-section and infinite length normal to that plane. The second is a three-dimensional (3-D) axisymmetric model consisting of a short thin cylinder capped by thin disks. In both models, transfer matrices relate state vectors of tractions and displacements at two segment boundaries. The time interval from pressure initiation to failure of its material measures the capsule's effectiveness as a confining boundary.
