Abstract: In this article the model of fracture of thin plates with cracks, which is a continuation and generalization of rocket fuel components model (Leonov–Panasyuk–Dugdale) and based on the idea of plastic zone at the crack tip as the areas in which deformations occur on a rigid scheme of Prager flow.

Keywords: rigid-plastic stream, thin-walled plate, crack, model of Leonov Panasyuk–Dugdale, plastic deformation, volume density of energy dissipation, Fredholm equation, method of “small parameter”.
