Nonlinear Theory Of Elasticity

a method for calculating the stress-deformed condition of the packing element shells reinforced with a system of metal tapes is proposed. The whole process of deformation of the shell under the influence of internal overpressure is conventionally divided into four stages. For each stage, the scheme of deformation of the shell is considered and the solution of the problem is given on the basis of the nonlinear theory of elasticity and the theory of soft shells. All stages of shell deformation considered in this paper are illustrated by the calculation scheme. An example of shell calculation with specified characteristics and deformation conditions is given.
