The low transverse moduli in Fiber-reinforced composite plates and shells manifest a greater susceptibility to transverse shear and normal deformations. As a result, the rangeof application of classical theory for this class of structures is abbreviated vis a' vis those fabricated of homogeneous, isotropic materials. To extend this range, transverse shear deformation must be included as its effect on flexural behavior can be pronounced. For example, classical theory predictions of lowest flexural frequencies of vibration of laminated plates and shells can be significantly higher than the actual frequencies if appreciable shear is present. Modifications ofclassical theory to account for shear deformation fall within the the realm of first-order shear deformation (FSD) theories.
