Aluminum alloys are considered a lot in the automotive and aerospace industry because of their high strength to weight ratio. In this manuscript, the gas forming process of aluminum AA6063 tubes at high temperatures up to 500°C is investigated, through experimental and numerical tests. Therefore, an experimental setup is prepared and so, tube specimens are formed in a die with square cross sect...

Abstract In this study, a new test method using protruding punch was proposed, that can separate bending and stretching deformations. test, the blank makes simultaneous contact with head shoulder to ensure constant angle during test. After contact, increasing stroke increases amount of stretch deformation without changing deformation. addition, control inflow materials by controlling BHF, it is...

Applying ultrasonic vibration in sheet metal forming can change its mechanism and improve formability. The uniaxial tensile bulging limit experimental setups were designed to study the relationship induced by excitation, results under different conditions analyzed. It was found that has effects on left right sides of diagram (FLD). Under same frequency, maximum increment major strain is about 9...

Metal sheet anisotropy is the directional dependence of mechanical properties. It key factor that must be considered when using numerical simulation to predict any manufacturing process involves plastic deformation. The strain ratio, also known as Lankford coefficients or R values, together with forming limit curves (FLC), are industry standards for assessing formability metals. Complete experi...
