Abstract

The paper is devoted to some featured lay-up solutions for optimized composite VAT plates under such conditions as buckling, postbuckling (within the von Karman limits) or large-deflection postbuckling (beyond the von Karman limits). The corresponding optimality conditions are theoretically analyzed. The possible locally orthotropic solutions are identified and discussed. For the solutions the local orthotropy axes coincide with the principal (generalized) curvature axes.
