Abstract
In this research, 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 Bauschinger effect factor, 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.
