Application of the BST Strain Energy Function to Torsion of a Circular Cylinder

Abstract

The problem of torsion of a circular cylinder is solved with the aid of a new strain energy density function. The results obtained are used to predict data of Rivlin and Saunders on natural rubber in simple torsion and torsion with extension. It is shown that the new s train energy function correctly describes the torsional couple and the normal load data from parameters obtained in simple tension.
