Abstract

This paper discusses the use of high-performance incompatible, enhanced-strain and hybrid stress elements for the St Venant torsion and bending of composite prismatic shafts, formulated in terms of the warping function. The properties of
the shaft are uniform along its length but piece-wise constant and orthotropic across its cross-section. In order to analyse composite shafts whose microstructural details are difficult to be modelled directly by finite element discretisation, the
two-scale asymptotic (or mathematical) homogenisation approach is also discussed; the resulting equilibrium equations can be readily solved by the aforementioned high-performance elements.
