摘要：

Three-dimensional exact solutions of the theories of elasticity pertaining to the static analysis of doubly curved (DC) antisymmetric angle-ply composite shells of rectangular planform have been derived. The method of exact solutions can be used in a straightforward manner to find the numerical values of exact solutions for any fiber orientation angle in the layers of the antisymmetric angle-ply shells. The exact solutions of displacements and stresses in the spherical antisymmetric angle-ply shells for some modes of deformations in which the magnitude of the fiber orientation angle is 45 degrees cannot be used for other fiber orientation angles and vice versa. Verification of a simple finite element model of the shells with the exact solutions derived here reveals that the derived exact solutions may serve as the benchmark solutions for DC antisymmetric angle-ply composite shells of rectangular planform.
