Stress distribution in a cross section of container for long-term storage of high-corrosive media

On the basis of the predicted effective elastic moduli for polymer concrete and obtained new exact analytical solutions to problem on equilibrium state of thick-walled heavy combined horizontal anisotropic cylinder, which is fixed on external lateral surface, the stress states of containers for long-term storage of high-corrosive solid and liquid media were investigated. External cylinders of containers were usually produced by fiber-glass plastics and coaxial internal one by polymer concrete. Influence of gravity forces and contact pressure on distribution of stresses in cross-sections is analysed, and an initial strength analysis of containers was cared out on the basis of multicriteria approach.
