An Investigation of Stresses and Strains in an Internally Pressurized, Composite-Jacketed, Steel Cylinder
Abstract
This report presents the results of a theoretical and experimental investigation of the effects on bore strain when a portion of the wall thickness of a steel cylinder is replaced with organic composite material. The pressure vessel is pressurized internally and the bore strain is theoretically predicted and experimentally measured as a function of wall ratio. Theoretical results for various ratios of steel to composite, from all-steel to all-composite, are given. The theoretical solution was obtained by equating the hoop strain of the steel with the hoop strain of the composite at the material interface. Lame's stress solution was used as input for the steel hoop strain, whereas Lekhnitskii's stress solution obtained for orthotropic cylinders was used as input to the composite hoop strain equation.
