Abstract

The purpose of this study is to calculate the torsional rigidity and maximum shear stresses of arbitrarily shaped orthotropic composite or functionally graded material sections on the basis of a hybrid finite element approach. A hybrid finite element based on a Hellinger-Reissner functional is presented. A set of numerical examples is solved to verify the proposed method, and a parametrical study is also performed.
