A STRESS-ANALYSIS MODEL FOR COMPOSITE COAXIAL CYLINDERS

An analytical model describing the elastic response of a system of coa xial thick-walled cylinders in contact is presented. The materials fro m which the cylinders are constructed must exhibit orthotropic elastic ity. The loading can be uniaxial tension, torsion or internal pressure . The model allows inter-and intralaminar stresses to be determined. E xamples of applications include pipes and light weight drive shafts re inforced with a helical winding, composite pressure vessels and single cells from fibrous plants such as flax and hemp.
