Explanation:
Machines or structural components inevitably contain stress raisers such as holes that can serve as fatigue crack initiation points. Accurate evaluation of the stress concentration factor (SCF) and stress fields at the stress raisers becomes the prerequisite for structural design and service life prediction. Pioneer analytical solutions for SCFs at circular and elliptical holes in infinite thin plates were obtained by Kirsch [1] and Inglis [2]. Complex variable solutions for the same problem were obtained later [3,4,5]. Rational solutions were reported for holes and notches in infinite thin plates and empirical formulae were proposed for more practical cases [6,7,8,9,10,11,12]. However, these theoretical solutions and empirical formulae were mainly obtained within the two-dimensional (2D) frame.
