Abstract: Equations are derived for stress concentration near a crack of closed contour lying in a plane. A system of one-dimensional integral equations for the concentration factor is obtained. The right sides of the equations contain the initial approximation–a solution of the problem of a circular crack whose sides are acted upon by nonaxisymmetric loading.
