We obtained resolving equations of finite element method to calculate the three-layer shells taking into account the creep of the middle layer. The outer layers of the shell are considered elastic and isotropic. We investigated the influence of curvature of a shell on the growth of deflection due to creep. The example of calculation is given for a spherical shell, hinged along the contour and loaded by uniformly distributed load. It was found that with increasing of curvature of the shell influence of creep on deflection has reduced.
