Abstract

This paper presents an exact flexural analysis of rectangular simply supported single-layer and two-layer cross-ply plates of bimodulus materials. The governing equations of a bimodulus plate based on a higherorder shear deformation theory are simplified from the composite plate. The present analysis of displacements in flexure is compared with Bert's results and Turvey's results which are based on Mindlin plate theory. The in-plane stress and bending stress are included in the present study. All the present numerical results are compared with the Mindlin plate theory (first-order plate theory) results. From those comparisons, the effects of higher-order shear deformation terms on the neutral surface locations and the flexure displacements can be observed.
