Abstract

This project work is concerned with the study of an Isotropic, Incompressible hollow cylinder deforming under pure azimuthal shear loading. The analysis resulted into a non-linear second order ordinary differential equation for the determination of the angular displacement. The resulting solution of the boundary value problem gave an equation which needed the wolfram Alpha software for the  determination of the analytic solution of the angular displacement. Relationship between the displacement, stress components and the material parameter for hardening and softening is shown and the effect of change on the material parameter on the angular displacement is illustrated.

Keywords: Angular displacement, deformed radius, shear strain, displacement gradient, shear stresses
