Abstract

This paper is proposing a method for determining the optimum stacking in a composite laminate material using finite elements method program for a specific application (the skin panel used for the adaptive wing). The main area of application for this method refers to the wings of the adaptive aircrafts, where the material of the wing's skin is requested to provide good strength while allowing large deformations. This optimization can lead to the reduction of the technological and operational costs. The analysis and result interpretation can then be extrapolated to similar materials with bigger plies stacking..
