Shear behavior of thin plain weave composites subjected to transverse shear Conference Paper uri icon


  • The effective properties for the textile composite laminates are usually obtained in terms of the engineering constants predicted for the bulk material. Since the textile composites have a complex microstructure, it is more accurate to predict the laminate stiffness properties directly from the microstructure. Several attempts have been made to predict the effective extension, flexure and shear properties of the laminates. The extension and flexure properties are easier to predict compared to the shear properties. This is because of the shear-flexure coupling that arises from the plate equilibrium. Earlier attempts in the literature to predict the effective shear properties resulted in significant errors because of the approximate boundary conditions. The current paper derives the correct boundary conditions based on the superposition principle to predict the effective shear properties for textile composites. Several plain weave configurations were analyzed to determine the effective shear properties. Also the mechanical behavior under transverse shear was characterized in terms of the maximum stresses.
