Abstract

Here, the supersonic flutter behavior of flat panels made of functionally graded materials is studied. The structural model is based on first-order shear theory and material properties are assumed to be temperature dependent and graded in the thickness direction. The aerodynamic force is evaluated by considering the first-order high Mach number approximation to linear potential flow theory. The variation of critical aerodynamic pressure is highlighted considering different parameters such as plate thickness, aspect ratio, power law index of functionally graded materials, temperature-dependent material properties. It is seen that the volume fraction index plays a significant role on the critical flutter speed under thermal environment.
