The article deals with the problem of determining the stress-strain state of a three-layer cylindrical shell with axisymmetric loading, taking into account the creep of the middle layer. The derivation of the resolving equations is given, as well as the solution of the test problem for the construction with polyurethane foam filler. The problem is reduced to a system of two differential equations, which is solved by the finite difference method in combination with the Euler method.
