Dynamic stresses in the vicinity of a crack along the cylindrical surface

By using the method of boundary integral equations combined with the method of small parameter, we solve the problem of low-frequency loading of a shallow crack along a cylindrical surface in an infinite elastic body. The distributions of the modes I–III stress intensity factors along the contour of the defect are obtained for different values of crack curvature and wave numbers. __________ Translated from Fizyko-Khimichna Mekhanika Materialiv, Vol. 42, No. 4, pp. 108–113, July–August, 2006.
