on predicting small fatigue Crack growth and fatigue life from long Crack Data in 2024 aluminium alloy
International Journal of Fatigue, 2003Co-Authors: M D Halliday, Chris Cooper, P Poole, P BowenAbstract:Small fatigue Crack growth Data for Cracks growing from constituent particles under constant amplitude loading are presented for the aluminium alloy 2024-T351. Confidence bounds are obtained for the small Crack growth rate Data. Fatigue Crack growth and fatigue life are predicted using a stochastic choice of growth rate from within these bounds for successive increments of Crack growth. A pragmatic approach is adopted to extend the analysis so that fatigue life prediction can be made from long Crack growth Data. Comparisons are made between fatigue lives reported in the literature for plane and notched samples and predictions obtained using the present analyses. Reasonably good agreement is obtained for both the shortest fatigue lives and for the spreads in fatigue lives.

Methodology for Evaluation of Residual Stress Effect on Small Corner-Crack Initiation and Growth
Materials, 2019Co-Authors: Jun Won KangAbstract:The growth behavior of a naturally initiated corner Crack under a uniform residual stress field is investigated in this study. A convenient method is proposed to induce and evaluate the uniform residual stress field for a beam-type specimen. Fatigue tests are conducted with a rotary bending fatigue machine to investigate the growth of the corner Crack. For this reason, a cylindrical specimen, which is typically used for rotating bending tests, is modified into a beam specimen. The corner Crack growth behavior under residual stress is evaluated based on linear elastic fracture mechanics (LEFM) and compared with long through Crack Data. The test results verify that the corner Crack growth under residual stress can be effectively evaluated by LEFM and estimated using long Crack Data.
