Antisymmetric Bending Analysis of Symmetric Sandwich Plates Including Transverse Shear and Normal Effects

Abstract

Antisymmetric bending analysis of sandwich plates with symmetric and balanced laminated faces and an orthotropic core is presented here. The transverse shear and normal strain and stress effects on bending of such sandwich plates are considered. A set of twelfth-order governing equations and consistent boundary conditions are given from a mixed variational theorem. The response of square sandwich plates with fully simple supports subjected to transverse sinusoidal loading is evaluated. The numerical results are compared with elasticity solutions and results obtained from other theories. The present theory is found to agree closely with three-dimensional elasticity solutions.
