  • Stress Intensity Factors for circumferential semi-elliptical surface cracks in a hollow cylinder subjected to pure torsion
    Predan, Jožef ; Močilnik, Vinko ; Gubeljak, Nenad
    The Stress-Intensity Factor for the circumferential semi-elliptical surface cracks in a hollow cylinderćs cross section under torsion is calculated using a finite-element technique. The configuration ... of the semi ellipse follows the standard notation of the outer surface crack-lengths and the crack depths. The compendia for the Stress-Intensity Factor solutions for Mode II, Mode III and both mixed modes are given for the broader aspect ratios and relative crack-depths than previously available. The magnitude of the Stress-Intensity Factor of Mode II near the free surface becomes more significant for stable crack-initiation than that of Mode III at any point along semi-elliptical crack.
