In order to obtain a simplified vibration theory for curved sandwich plates in a thermal environment, differential equations are derived from a small deflection Donnell-type theory for the displacements of shallow cylindrically curved sandwich panels, e.g., honeycomb panels, with thin isotropic facings. It is assumed that normals to the undeformed middle surface remain straight lines but not necessarily normal to the deformed middle surface and that the transverse deflection does ...
An attempt was made to establish the correlation between surface waviness of honeycomb core panels and the face wrinkling attendant upon the panels when subjected to compressive forces. Tests were conducted with honeycomb sandwich edgewise compression specimens with controlled initial surface waviness. (Author)
