BENDING THEORY FOR MULTILAYER ORTHOTROPIC SANDWICH PLATES

The governing equations on bending of multilayered orthotropic (both core and facings) sandwich plates are developed through the use of variational methods. The plate is assumed to consist of j facings and (j - 1) cores, having different thicknesses and possessing different orthotropic elastic properties. In-plane stresses in the cores are neglected as is the variation of stresses across the facings. The developed theory is an extension of that given in Ref. 7. © 1968 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
