Torsional Stresses

Abstract

Our study of stresses would not be complete without examining the stresses that can occur within a structural element due to torsional or twisting effects. In this programme we are going to determine the governing equations that will define the behaviour and response of an element which is subjected to torsion, and see how these equations can be applied to the solution of a number of common problems. A complete treatment of torsional stress for all shapes of structural sections can be quite complex and is beyond the scope of this text. We will however look at the analysis of circular sections whereby the fundamental analytical expressions can be developed and the basic principles established.
