Abstract

A comparative approach and mathematical modelling is done for the purpose of solving creep problem in the spherical shell made up of different materials subjected to uniform internal pressure. The technique of generalization of strain measures and Seth’s transition theory is used to deal with the nonlinear effects arising from creep. The method is independent of various adhoc assumptions like creep law, yield criterion, axial strain rate, infinitesimally small deformation etc. Results are compared for different type of materials and depicted graphically.
