Abstract

Finite element micromechanical models have been developed to investigate the behaviour of unidirectional fibre reinforced composites with thermal residual stresses subjected to transverse and axial shear loading. Appropriate Representative Volume Elements (RVEs) have been chosen in order to apply both thermal and shear boundary conditions simultaneously. Effects of fibre volume fraction and fibre packing arrangement on effective shear moduli were studied. The state of stress was highly influenced by fibre packing, for both the transverse and axial shear cases. The predicted results for effective shear moduli show a good agreement with other analytical models. Elastic-plastic results demonstrate that initiation of yielding in
