Stability of Flat, Simply Supported, Rectangular Sandwich Panels Subjected to Combined Inplane Loadings. Volume 1. Theoretical Development
Abstract
The general stability of flat, rectangular sandwich panels loaded by combined biaxial compression, biaxial edgewise bending and edgewise shear is investigated. The analysis is applicable to sandwich structures having isotropic face sheets and orthotropic cores. The analysis procedure is based upon a linear potential energy formulation and the Ritz method of discretization. For the case of simply supported boundaries, it is shown that the equations can be uncoupled in such a way that a numerical solution is obtained in an economical fashion. A number of verification results are presented. Comparisons are made between the numerical solutions and the predictions of certain interaction formulas which are commonly employed in sandwich panel design.
