Stress concentration equations for straight shank and countersunk holes in a large plate subjected to various loading conditions encountered in service were developed from three-dimensional finite element solutions. For straight shank holes, three types of loading: remote tension, remote bending, and pin loading were considered; and for the countersunk hole only remote tension and bending loads were considered. The equations are within one percent of the finite element results and are valid for isotropic materials with Poisson’s ratio of 0.3.
