✦ Synopsis

The finite element-alternating method is used to obtain Mode I stress intensity factors for semielliptical surface cracks centered along the bore of a hole in a large plate of finite thickness. The variation in stress intensity factor around the crack perimeter is provided for two loading configurations: remote uniaxial tension and a crack face pressure described by a third order polynomial. It is suggested that the tabulated solutions for the crack face pressure loading represent "general" results which can be used with linear superposition to compute stress intensity factors for many other practical loading configurations. Two example problems describe application of the superposition procedure with the crack face pressure results.
