| Abstract: | The article deals with the spatial problem of the limit equilibrium of an isotropic elastic body weakened by a three-dimensional crack with an almost planar surface. At infinity the body is subjected to tensile constant forces of intensity p. With the small parameter method this problem is reduced to a series of problems for a body with a disk-shaped crack. The dependence of the critical load on the magnitude of the deviation of the crack surface from planeness is obtained.Translated from Teoreticheskaya i Prikladnaya Mekhanika, No. 20, pp. 21–25, 1989. |
