Abstract : It has been recognized for some time that in many cases rib stiffness plates are more efficient then unstiffened ones. We consider a plate optimization problem where the plate thickness and the direction and concentration of two mutually orthogonal fields of integral stiffeners are used as design variables. In order to perform a structural analysis for the elastic case, a smear-out process is carried out, and the rigidity tensor for an anisotropic plate is obtained.
