The effect of cryogenic and high temperatures on the nonlinear straining processes of the non-shallow spherical shells under external axisymmetric and non-axisymmetric pressure has been numerically investigated. Along with this, the limit loads buckling have been determined. Cases of substantial differences between reached and initial temperatures are considered. According to the calculations, a diversity of the buckling forms in the analyzed problems has been shown. It has been found that the largest critical loads for the deep spherical shell are observed at cryogenic temperatures for the analyzed thermal and force loading and its values decrease considerably at higher temperatures. The calculations have shown a significant dependence of the stress-strain state of the thermo-stressed segments on the accounting completeness of the temperature dependence of the material characteristics.
