2021-9-29 · The simplified stress–strain curves of five specimens were obtained by GB/T 228-2002 (eqv ISO 6892: 1998) and the stress strain constitutive relation of the 7N01 aluminum alloy needed in the ...
2005-12-1 · In this paper, the tensile stress–strain response for AA5754 and AA5182 aluminum sheet alloys tested under quasi-static (QS) conditions (3.3 × 1 0-3 s-1) and strain rates of 600, 1100 and 1500 s −1 is presented. The elevated strain rate testing was performed using a tensile split Hopkinson apparatus equipped with momentum trapping ...
2016-9-21 · Damage initiation. Metal sheets and thin-walled extrusions made of aluminum alloys may fail due to one or a combination of the following failure mechanisms (Hooputra et al. 2004): ductile failure due to nucleation, growth, .
Aluminium 6061-T6 is a sub-category of the 6061 alloy, one of the most widely used aluminium alloys. The 6061-T6 alloy is used in applications where high strength to low weight ratios are critical such as the aircraft and aerospace industries. It is the way the base Aluminium 6061 is treated that give Aluminium 6061-T6 it particular ...
The aim of this study is to show the effect of the strain-rate on the forming limit strain of an aluminum alloy A5052 sheet and a mild sheet SPCC. Biaxial stretching test was carried out. The prescribed strain path was linear path or that with directional change in straining. The sheet was pre-strained by uniaxial tension in the latter path.
2019-11-8 · Aluminum alloy sheet metal is characterized by its good weight to strength ratio. However, one shortcoming of aluminum is its low malleability compared to mild which is widely used in sheet metal forming. Thus, costly multi-step manufacture processes are required to obtain intricate product geometries with aluminum alloys [1].
