Investigating dynamic stability behavior of sandwich plates with porous core based on a numerical approach
Zhihui Zhu and Meifang Zhu

    A numerical approach for dynamic stability analysis of sandwich plates has been provided using Chebyshev-Ritz- Bolotin approach. The sandwich plate with porous core has been formulated according to a higher-order plate. All of material properties are assumed to be dependent of porosity factor which determines the amount or volume of pores. The sandwich plate has also been assumed to be under periodic in-plane loading of compressive type. It will be shown that stability boundaries of the sandwich plate are dependent on static and dynamical load factors, porosity factor, porosity variation and core thickness.
