Аннотация: In this work, based on the representation of the Papkovich –Neiber displacement and stress through 3harmonic functions, dual integral equations are obtained, the solution of which is reduced to finding oneHelder function. To find this function, a singular integral equation with a Cauchy kernel of the 1st kind isobtained. The solution of this integral equation, proposed by the method of V. D. Kuliyev, is reduced tothe Fredholm integral equation of the 2nd kind with a continuous kernel. The main parameter of themechanics of linear fracture of the stress intensity coefficient is determined and a numerical analysis iscarried out. When the crack of a normal fracture is located in an infinite elastic medium, it is shown thatboth components of the displacement vector are nonzero. This result suggests that the crack is an oblateellipsoid
