An analytical method on the creep problems of general moderately thick shells of revolution subjected to asymmetrical thermal and/or mechanical loads is developed in consideration of the effect of shear deformations. The Norton-Bailey type equation having the thermal effect multiplier by Arrhenius is employed for the constitutive relation. The fundamental equations on the creep problems derived for incremental values are numerically solved by a finite difference method and the solutions are obtained by integration of the incremental values. As a numerical example, the creep deformation of a cylindrical shell under an asymmetrical thermal load and subject to an internal pressure is analyzed, and the results are compared with those from the classical theory which neglects the effect of shear deformations. It is shown from the comparison that in the creep problem of moderately thick shells the difference between solutions from the present theory and those from the classical theory becomes significant.
