Inelastic buckling of rectangular sandwich plates (Q675437)

An analytical study of buckling of rectangular sandwich plates, stressed uniaxially by uniform shortening beyond the elastic limits of component materials, is presented. The analysis is based on the inelastic behavior according to both the \(J_2\)-incremental and \(J_2\)-deformation theories of plasticity. Taking the loaded edges as simply supported, the governing equations are solved for (a) plates simply supported on all four sides, and (b) plates simply supported on three sides and free on the fourth side.
