Analytic Model Development for Ceramic Gun Tubes

Abstract

The equations for calculating the probability of failure for an internally pressurized ceramic tube are straightforward and well defined in the literature. The most common solution is for a tube subjected only to an internal pressure. This approach neglects any external pressure, over wrap, or sheathing system that may be used to maintain or promote a beneficial compressive pre-stress. The current research has focused on the development of a model, based on elasticity theory, of a sheathed ceramic tube augmented with probability of failure calculations used to calculate stress, strain, and probability of failure of the ceramic tube component. The model calculated the Weibull probability of failure for volumetric- and surface strength- limiting flaws with the consideration of predicted (isothermal, mechanical, or combined) stress states on the surfaces and throughout the volume.
