Deformation of working shells of mixing devices in the production of concrete for underground construction

The paper presents the calculation of the stress-strain state of the composite shell of the mixing device in the production of concrete used in underground construction. A mathematical model obtained earlier by the authors, which develops due to the influence accounting of the temperature field, was used. The problem was solved in the linear formulation with varying rigidity characteristics of separate layers as a result of an aggressive environment. The calculations results are shown.
