Identification of strength parameters for a high-pressure vessel wound by fibre reinforced composite materials

摘要

In this paper a high-pressure vessel (HPV) is assumed to be wound by a set of macroscopically orthotropic layers constructed respectively from unidirectional laminae. The formulae for the three-dimensional stress fields in the vessel areestablished. In the light of the Tsai-Wu failure criterion, the first ply failure internal pressure (FPFP) is calculated. Using this measured FPFP, the vessel strength parameters are identified by Bayesian methods.
