عنوان انگلیسی The Investigation of Modelling Material Behavior in Autofrettaged Tubes Made from Aluminium Alloys
چکیده انگلیسی مقاله Normal 0 false false false EN-US X-NONE AR-SA The ratio of compression yield strength to the initial tensile yield strength is called Bauschinger effect factor, BEF. A nonlinear strain hardening mathematical model is proposed for 7075 aluminium alloy (A7075). Uniaxial tension-compression experimental data are used to figure out a suitable model to study the BEF. Hence, uniaxial tension-compression tests on some specimens having 12.5 mm and 6 mm diameters were carried out by an Instron servohydraulic machine and were compared. In this paper several factors including Young’s modulus, the amount of offsets to determine yield point and BEF were studied. Besides, BEF in the aluminium tubes made from alloys of A5083 and A7075 were compared. This model will be employed to predict residual stress and fatigue life in autofrettaged tubes.
