Thermal instability of functionally graded deep spherical shell

摘要: Thermal instability of deep spherical shells made functionally graded material (FGM) is studied in this paper. The governing equations are based on the first-order theory and Sanders nonlinear kinematics equations. It assumed that mechanical properties linear functions thickness coordinate. constituent shell to be a mixture ceramic metal. analytical solutions obtained for three types thermal loadings including uniform temperature rise (UTR), radial (LRT), (NRT). Results validated with known data literature.
