Effect of shear correction factor on response of cross-ply laminated plates using FSDT

Abstract

The results of the first-order shear deformation theory (FSDT) depend on the choice of the shear correction factor. In a companion paper, the authors presented a unified general formulation of all higher-order theories for geometrically nonlinear response of cross-ply plates, based on a single polynomial expansion of displacements in the thickness coordinate, z. It includes 10 models available in the literature as special cases. In the present paper, numerical results for the static, vibration, and buckling of the FSDT are compared with the elasticity solution and /or a higher-order theory solution, to investigate the effect of choice of the shear correction factor on the response of composite and simply supported rectangular plates. © 2005, DESIDOC.
