Abstract
We solve the problem of torsion of an elastic cone weakened by a spherical crack under the action of an impact moment applied to the vertex. For the solution of the problem, we use an approach based on the method of discontinuous solutions. The problem is reduced to a one-dimensional integrodifferential equation for the unknown jump of displacements in the space of Laplace transforms. An approximate solution of this equation is obtained by applying the procedure of discretization of the investigated equation in time in combination with the method of orthogonal polynomials. As a result, we deduce a formula for finding the stress intensity factor.
