Research ArticleOpen accessIn the abstractHow Does The Bone Shaft Geometry Affect its Bending Properties?Kaveh PourAkbar Saffar, Nima JamilPour, Seyed Mohammad RajaaiIn this research, ten fresh specimens of sheep tibiae were provided from slaughtered animals. Whole bone specimens were loaded in three-point bending according to standard wet bone test protocols. Mechanical properties were determined and compared with the results which were obtained from two dry bone tests. The results showed that fracture bending moment and bone extrinsic stiffness had significant relations … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 8,154 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNonlinear Models and Experimental Investigation of Lifetime History of HSC Flexural BeamsK. Masti, A.A. Maghsoudi, R. RahgozarThe nature of fracture in high strength concrete is brittle and therefore, the investigation behavior of flexural high strength concrete (HSC) members is important. This paper describes the deflection, strain and energy ductility and the lifetime history of experimental and theoretical analysis of six caste reinforced HSC beams with different percentage of ρ and ρρ'. The beams were loaded incrementally … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 6,756 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPressure-sensitivity Effects on Toughness Measurements of Compact Tension Specimens for Strain-hardening SolidsAbdulhamid A. Al-AbduljabbarThe path-independent J-integral is used as a fracture prediction criterion for loading beyond the elastic limit as Linear Elastic Fracture Mechanics (LEFM) cannot be applied. While J was originally defined from an energy perspective, it was demonstrated that it could be inferred from load-displacement diagrams. Therefore, the Compact Tension (CT) specimen testing is used to compute J for materials. In … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,660 accessesView PDF Cite
