Abstract On the basis of the finite element method (FEM) the authors devised an effective apparatus of numerical investigation of processes of failure of axisymmetric complexly shaped bodies under plane strain, induced by propagation of initial cracks in them. This apparatus was worked out on the basis of the use of special finite elements approximating the existence of a crack from the condition that the stresses normal and tangential to its path are equal to zero. The article suggests new modifications of the method of separate calculation of stress intensity factors and of an algorithm for solving problems of linear fracture mechanics when the path of crack propagation is not known. The reliability of the results obtained with the application of the new method and realizing its complex of programs was confirmed by the solution of control problems. An illustration of the possibilities of the method and of the complex is the calculation of the load bearing capacity of a permanent joint of a cylindrical glass shell with a metallic end cap.
