Abstract

In this article, an investigation of the effect from the transverse elastic moduli of the lamina on the dilatation and the through-thickness Poisson’s ratio in the angle-ply laminates is presented. Based on the classical lamination theory and the generalized Hook’s law, a dimensionless analysis has been used to study the influence of the various transverse elastic moduli E₂ and E₃ of the lamina on the dilatation and the through-thickness Poisson’s ratio in angle-ply laminates. The results from this dimensionless analysis provide a set of general guidelines for designing and evaluating the values of the through-thickness Poisson’s ratio and the dilatation of the angle-ply laminates to meet various requirements in engineering applications.
