The theoretical solutions are obtained for the three-dimensional(3-D)stress field in an infinite isotropic elastic plate with a through-the-thickness circular hole subjected to shear load at far field by using Kane and Mindlin′s assumption based on the stress function method.Based on the present solutions,the characteristics of 3-D stress field are analyzed and the emphasis is placed on the effects of the plate thickness and Poisson′s ratio on the deviation of the present 3-D in-plane stress from the related plane stress solutions,the stress concentration and the out-of-plane constraint.The present solutions show that the stress concentration factor reaches its peak value of about 8.9% which is higher than that of the plane stress solutions.As expected,the out-of-plane stress constraint factor can reach 1on the surface of the hole when the plate is a very thick one.

The theoretical solutions are obtained for the three-dimensional （3-D） stress field in an infinite isotropic elastic plate with a through-the-thickness circular hole subjected to shear load at far field by using Kane and Mind- lin＇s assumption based on the stress function method. Based on the present solutions, the characteristics of 3-D stress field are analyzed and the emphasis is placed on the effects of the plate thickness and Poisson~s ratio on the deviation of the present 3-D in-plane stress from the related plane stress solutions, the stress concentration and the out-of-plane constraint. The present solutions show that the stress concentration factor reaches its peak value of a- bout 8.9% which is higher than that of the plane stress solutions. As expected, the out-of plane stress constraint factor can reach 1 on the surface of the hole when the plate is a very thick one.
