Abstract
The present investigation concerns minimum weight design of composite plates in the presence of cutouts undergoing large amplitude oscillations. The Ritz finite element model using a nine-noded C0 continuity, isoparametric element along with a higher order displacement theory which accounts for parabolic variation of transverse shear stresses is used to predict the dynamic behavior. The optimal value is found by using a Genetic Algorithm with tournament selection. Results have been obtained for various cutout geometries like square, rectangular, circular and elliptical in the large amplitude range.
