Abstract
On the basis of an analog of the Leonov—Panasyuk—Dugdale δ-model and with the use of the initial equations of the general moment theory of shells the article deals with the limit equilibrium of a closed infinite cylindrical shell which has a transverse blind crack. On the basis of the generalized dislocation method the problem is reduced to a system of two singular integral equations whose solution is constructed with a view to the conditions of finiteness of the stresses in the vicinity of the crack. For a shell uniformly tensioned at infinity the article investigates the dependence of the dimension of the plastic zone and of the crack opening on the external load.
