Residual Stresses in a Prestressed Steel Pressure Vessel Wrapped withMultilayered Composites

摘要

This report presents an analytical solution for predicting residual stresses in asteel pressure vessel wrapped with a multilayered composite jacket. The numerical results for the hoop stresses before and after complete unloading are obtained for a subscale test tube. The steel liner is elastic-plastic, and the composite layup (02902)4 consists of 16 layers made of graphite bismaleimide produced by Fiberite Corporation.
