Elastic-Plastic Analysis of a Steel Pressure Vessel Wrapped with Multilayered Composites.

摘要

An elastic-plastic analysis of stresses and strains in an internally pressurized, composite-jacketed cylinder is studied here. Each layer is orthotropic but with different material properties. Analytical expressions are derived for a steel pressure vessel wrapped with multilayered composites. Numerical results are obtained for three types of composite jackets. The interface pressure, hoop strains, and stresses in the liner and jacket are presented.
