Shear Moduli of Orthotropic Composites.

Abstract

The elasticity solution for a circular cylindrical body possessing rectilinear orthotropy under pure torsion is used to define an experimental approach to determine the shear moduli of orthotropic composites. Attention is focused on the transverse shear modulus of a unidirectional composite, which is not routinely measured in the characterization procedure. This property, as well as the longitudinal shear modulus, can be determined from the same specimen, which consists of transversely oriented unidirectional fiber reinforcement. The simulation of the theoretical displacement boundary conditions and failure tests are also discussed. (Author)
