Three-dimensional stress concentrations at elliptic holes in elastic isotropic plates subjected to tensile stress

The through-thickness variations of stress concentration factors along the wall of elliptic holes in finite thickness plates of isotropic materials subjected to remote tensile stress have been systematically analyzed using the finite element method. The three-dimensional stress concentration factor Kt is found to be a function of the thickness to root radius ratio B/ρ and the aspect ratio t (short to long axial length) of the elliptic hole under...
