A solution procedure for determining laminate configurations from lamination parameters

Abstract

The present paper shows a solution procedure for determining laminate configurations corresponding to in-plane and/or out-of-plane lamination parameters for symmetric and balanced laminates. The solution procedure is shown for the laminate with an infinite number of plies as well as that with a finite number of plies. As a numerical example of the present method, the laminate configurations with isotropic stiffness characteristics are obtained. A particular class of laminate configurations is also presented where the stiffness characteristics are isotropic with respect to both in-plane and out-of-plane stiffnesses.
