This paper contains a three-dimensional solution, exact within classical elastostatics, for the stresses and deformations arising in a half space with a semi-infinite transverse cylindrical hole, if the body -- at infinite distances from its cylindrical boundary -- is subjected to an arbitrary uniform plane field of stress that is parallel to the bounding plane. The solution presented is in integral form and is deduced with the aid of the Papkovich stress functions by means of an especially adapted, unconventional, integral-transform technique. Numerical results for the non-vanishing stresses along the boundary of the hole and for the normal displacement at the plane boundary, corresponding to several values of Poisson's ratio, are also included. These results exhibit in detail the three-dimensional stress boundary layer that emerges near the edges of the hole in the analogous problem for a plate of finite thickness, as the ratio of the plate-thickness to the diameter of the hole grows beyond bounds. The results obtained thus illustrate the limitations inherent 1n the two-dimensional plane-strain treatment of the spatial plane problem; in addition, they are relevant to failure considerations and are of interest 1n connection with experimental stress analysis.
