To increase the thermal resistance of various structural components in
high-temperature environments, research reports focusing nonlinear
axisymmetric response of thin FGM shallow spherical shells with ceramic –
metal – ceramic layers (S-FGM) under uniform external pressure and
temperature. Equilibrium and compatibility equations for shallow
spherical shells are derived by using the classical shell theory and
specialized for axisymmetric deformation with both geometrical
nonlinearity and initial geometrical imperfection. One-term deflection
mode is assumed and explicit expressions of buckling loads and
load–deflection curves are determined due to Galerkin method. Stability
analysis for a clamped spherical shell shows the effects of material and
geometric parameters, edge restraint and temperature conditions, and
imperfection on the behavior of the shells. The results were compared
with the P-FGM spherical shell symmetry axis (ceramic – metal).
