Displacement and Stress Analysis of Thick Rectangular Clamped Plates Using Third-Order Energy Functional

This study analysed the stress and displacement responses of an all-clamped rectangular thick plate subjected to a uniformly distributed load using polynomial functions. A shear deformation function was incorporated in determination general governing equations; hence, there is no need for correction factors. Approximate Polynomial Displacement Functions w, u, v all clamped plates subject transverse loading were obtained. Numerical results obtained equations from literature non-dimensional form displacements stresses (CCCC) at different aspect span-depth ratios determine efficiency this theory. The validated as they showed good agreement with by other researchers available literature. Hence, theory can be used reliable, concise, easy dependable means analysis plates. also indicate that ratio 100 above, classical (CPT) analyse plates, numerical values are approximately equal CPT.
