Abstract

In this paper, a refined shear-deformation theory for flexure of thick symmetric angle-ply laminates has been developed. Lamination-dependent thicknesswise distributions for in-plane displacements in terms of referenceplane variables are used. They are derived from a priori distributions for slopes of transverse shear stresses based on three-dimensional equilibrium equations in each ply. Performance of the present theory is evaluated by comparing the solutions with the exact elasticity solutions for simply supported cross-ply laminates subjected to sinusoidal loading. It is found that the present theory is quite accurate for a wide range of variations in the thickness and modular ratios.
