Description
Summary:An analytical method has been developed for determining the moment of destruction of thin coatings of pipes and spherical vessels, the material of which works at the stage of elasticity. The coating material has the property of deformation softening, that is, destruction with increasing deformation occurs in the process of stress drop. The properties of the coating material are described by convex-concave potentials both in uniaxial tension and in a plane stressed state. To determine the moment of destruction, the methods of the mathematical theory of catastrophes are used, which make it possible to find all the equilibrium positions of systems and the point of loss of stability of the deformation process.
