Thermal vibration of thick FGM spherical shells by using TSDT

The effects of TSDT on the thermal vibration of thick FGM spherical shells are investigated by using the GDQ numerical method. The c(1) term of nonlinear coefficient in TSDT displacement is included to obtain the dynamic GDQ discrete equations. Parametric variables for environment temperature, FGM power law index and calculated shear coefficient are used to study the main effects on the stress and center deflection. The calculated thermal deflection and stress data of time response and transient response are presented for the thick FGM spherical shells.
