End reinforcement and grips for anisotropic tubes

Abstract

A method of gripping and reinforcing the ends of anisotropic tubes for testing under combined axial load and internal pressure is analysed. Edge solutions for long, cylindrical, specially orthotropic shells are considered. The tube, reinforcement, and grips are then modelled as an assembly of short, parallel, multilayered, thin-walled, orthotropic shells. Theoretical results are presented for the stress distribution in a ± 75 degree filament-wound E glass/epoxy resin tube with circumferentially wound glass fibre reinforced ends.
