Effects of Unsteady Aerodynamic Pressure Load in the Thermal Environment of FGM Plates

Abstract

The effects of unsteady aerodynamic pressure load with varied shear correction coefficient on the functionally graded material (FGM) plates are investigated. Thermal vibration is studied by using the first-order shear deformation theory (FSDT) and the generalized differential quadrature (GDQ) method. Usually, in the FGM analyses, the computed and varied values of shear correction coefficient are the function of the total thickness of plates, FGM power law index, and environment temperature. The effects of environment temperature and FGM power law index on the thermal stress and center deflection of airflow over the upper surface of FGM plates are obtained and investigated. In addition, the effects, with and without the fluid flow over the upper surface of FGM plates, on the center deflection and normal stress are also investigated.
