CREEP AND CARRYING CAPACITY OF SHELLS,
Abstract
In this report certain problems are considered in the theory of the creep and carrying capacity of shells being plastically deformed (strained). The first chapter contains the general theory of the carrying capacity and creep of shells in the presence of strong high-temperature gradients. In it equations are given of equilibrium in a tensor form for shells made of isotropic and anisotropic viscous relaxing and herditary materials. The second chapter contains problems in the calculation of shells on the basis of a momentless theory, assuming that the material of the shell is subordinate to the linear law of the deformation of an elastic-viscous body, a medium as conceived of by A.Yu. Ishlinskiy, and the Boltzmann-Walther elastic-hereditary theory at a constant temperature. The third chapter contains the same problems as in the second chapter, but on the basis of the general moment theory of shells. For the mediums considered in the second and third chapters, the solution of creep problems for shells reduces to their elastic solution, multiplied by a certain characteristic multiplier, dependent upon time. Considering possible applications, we give a full set of formulas referring to these problems. (Author)
