Benachour","volume":44,"journal":"International Journal of Aerospace and Mechanical Engineering","pagesStart":692,"pagesEnd":696,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/6865","abstract":"In this paper fatigue crack growth behavior of\r\naeronautical aluminum alloy 2024 T351 was studied. Effects of\r\nvarious loading and geometrical parameters are studied such as stress\r\nratio, amplitude loading, etc. The fatigue crack growth with constant\r\namplitude is studied using the AFGROW code when NASGRO\r\nmodel is used. The effect of the stress ratio is highlighted, where one\r\nnotices a shift of the curves of crack growth. The comparative study\r\nbetween two orientations L-T and T-L on fatigue behavior are\r\npresented and shows the variation on the fatigue life. L-T orientation\r\npresents a good fatigue crack growth resistance. Effects of crack\r\nclosure are shown in Paris domain and that no crack closure\r\nphenomenons are present at high stress intensity factor.","references":"[1] Hoeppner, D.W., \"Industrial Significance of Fatigue Problems\", ASM\r\nHandbook, Fatigue and Fracture, vol. 19, p 1, 1996.\r\n[2] Paris, P.C., Gomez, M.P., and Anderson, W.P., \"A rational analytic\r\ntheory of fatigue\", The Trend Eng, vol. 13, pp 9-14, 1961.\r\n[3] Jones, R., Molent L., Pitt, S., and Siores, E., \"Recent developments in\r\nfatigue crack growth\", In: Gdoutos EE, editor.
