Abstract
An elastic state of a thin circular sector, when on the radial sides the condition of contact with rigid stamp without friction (conditions of smooth contact) is established and on the arch part of the contour normal and tangential displacements are given, is considered. In the earlier investigations [1-6] on the arch part of the contour of the sector 1) normal and tangential stresses, 2) normal stress and tangential displacement, 3) normal displacement and tangential stress were given. It has been shown, that in these cases, when the wedge angle opening tends to or 2 , the stresses have the singularity of r 1 type ( 0 at or 2 ) and the coefficients with such singularity in the conditions of general loading of the contour arch part in the first problem are different from zero, and in the second and third problems they vanish. Here the fourth case of loading of the arch part of the boundary sector is analized. The solution of the problem is built with the help of the method of separation of variables.
