The paper presents an efficient stiffness optimization approach to fully isotropic laminates with approximate isotropic behaviors respect toboth extensional and bending stiffnesses. Based on the Integral global minimization method, the layer orientation angles andthe layer thickness ratios are chosen as design variablesand the lamination parameters are minimized to get theopthnal designs. Example of laminate with approximatefully isotropic behaviors is presented, which has lessthan one-third the number of plies of a fully isotropiclaminate. 展开更多
