Deflection Stresses in Uniformly Loaded Simply Supported Plate
DEFLECTION AND STRESSES IN A UNIFORMLY LOADED, SIMPLY SUPPORTED, RECTANGULAR SANDWICH PLATE
A theoretical solution is presented for the deflection and stresses in a uniformly loaded, simply supported, rectangular sandwich plate. The solution is applicable to sandwich plates having an orthotropic core of arbitrary thickness and isotropic facings. The facings may be of equal or unequal thickness. Numerical results and curves are included.
The purpose of this report is to obtain formulas from which the deflection and stresses in a uniformly loaded, simply supported, rectangular sandwich plate may be computed. The sandwich plate is assumed to consist of isotropic facings separated by and bonded to an orthotropic core. The core is considered to have such a small loadcarrying capacity in the plane of the plate as compared to that of the facings that the normal stresses in the core in the plane of the plate and the shear stresses in the core on planes perpendicular to the facings and in directions parallel to the facings may be neglected. The analysis of the facings is based on the usual small deflection theory of laterally loaded plates.
