Optimization of Laminated Composite Plates

Abstract

Optima laminate configurations for laminated rectangular plates under transverse and buckling loads are investigated. Laminate thickness and fiber orientation are treated as design variables, the thickness laminate being variable along the plate. A fully stressed iterative procedure and a quadratic failure criterion have been applied in order to get the minimum weight plate using strength as a design criterion. A finite element method accounting for in- plane and interlaminar stresses has been used. Results for thin and thick plates, different boundary conditions and some types of loading are shown. Keywords: Stress loads; Strength; Structural properties; Composite materials; Optimization; Finite elements.
