ABSTRACT = {Post-buckling and panel flutter behaviors of ceramic-metal FGM plates are studied for the skins of 
supersonic aircrafts. The effects of asymmetric material and temperature distributions, as well as the 
aerodynamic loads, on the thermo-mechanical response of FGM plates are discussed using finite 
element simulations. The aero-thermo-elastic model is established by using the simple power law 
material distribution, the rule of mixture for material effective properties, the nonlinear Fourier 
equations of heat conduction, von-Karman strain-displacement nonlinear relations, and the piston 
theory for supersonic aerodynamics. The finite element equations are established using the first-order 
shear deformable plate elements. The thermal post-buckling equilibrium deflections are calculated 
from the reduced-order model, and the flutter stability is furtherly evaluated around these 
equilibriums. The post-buckling equilibriums are found asymmetric about the initial position of the 
plate, and the critical flutter speed from the post-buckling model is much higher than the linear flutter 
speed on the initial position. Numerical results show that the effect of thermal gradient on the postbuckling deflection of FGM plate decreases with the increase of the material gradient index. With the 
increase in volume fraction of ceramics (decrease in volume fraction index), the critical flutter 
aerodynamic pressure of the ceramic/ metal plate increases. The flutter response amplitude increases 
with the increase in volume fraction index.},
