✦ Synopsis

The object of this investigation is to determine if and how the presence of core materials, flexible in shear, affects the magnitude of variation of the stresses and deflection in orthotropic sandwich plates. The differential equations for an orthotropic sandwich plate are derived by a variational method and are solved by numerical integration. The solutions are checked against known analytical results for cases where shearing deformations are negligible. Various results are given which indicate the importance of shearing deformation and orthotropie elastic properties. A simple criterion is developed for deciding whether the flexible core will affect the behaviour of the sandwich plate.
