Abstract：This paper is concerned with the load-carrying capacity of circular sandwich panels subjected to central quasi-static loading. The panel consists of two metallic face-sheets and a core made from metallic foam, and is fully clamped at the edges. The analysis is based on a newly developed yield criterion for the sandwich cross section. The large deflection response is estimated by assuming a velocity field, which is defined according to the initial deformation mode of flat panel and the boundary condition. A finite element simulation has been performed to validate the analytical solution. A parametric study is then carried out to examine the structural response. Good agreement confirms that the quasi-static behavior of circular sandwich plates is well captured by the analytical model
