报告内容摘要：    

In nature, many structures can be regarded as functionally graded porous (FGP) sandwich structures. Due to their outstanding properties such as high specific stiffness and strength, as well as their energy absorption capability, FGP sandwich structures find their potential applications in the aerospace industry for components of hypersonic vehicles and reusable launch vehicles.

Heretofore, research on the mechanical behaviors of FGP sandwich plates mainly focus on the blast resistance by means of simulation or experiment. Even if these FGP sandwich structures are designed for blast resistance, in most of their service life, they serve as load-bearing member. Therefore, the bending, vibration and buckling should be considered primarily. In this talk, the analytical solution to the free vibration of FGP sandwich plates is presented.
