The article proposes a mathematical model of deformation of conical shells with the possible development of long-term creep loading. Mathematical model of recorded as a functional of the total strain energy shell. Takes into account geometrical non-linearity, discrete rib arrangement of shear and torsion stiffness and lateral shifts. Conical shell model taking into account the creep of the material recorded in the form of the total energy functional deformation of the shell can be studied using the Ritz variational method, ie to investigate the stability reinforced conical shells, you can use the procedure described in the AA Ovtcharova To investigate the creep of the material used an iterative process.
