Tensile tests of Surfalex HF (AA6016A)

This dataset contains tensile test measurements of Surfalex HF (AA6016A), an aluminium alloy commonly used in automotive applications.

Tensile testing was performed at room temperature using a 5 kN Instron universal testing machine. The tensile tests were performed at a constant strain rate of 5e-4 per second and controlled with a Strain Master DIC system by LaVision. The gauge length of the samples was 25 mm long and 5 mm wide.

To study the anisotropy of the material, the samples were cut along different orientations with respect to the sheet rolling direction. Five angles were tested: 0, 30, 45, 60 and 90 degrees. The tensile specimens were polished and then thoroughly cleaned to obtain contamination-free surfaces. In order to perform DIC measurements, the specimens were painted with a white undercoating and a black speckle pattern.

Images were recorded at a frequency of 1 Hz during the tests and the DIC analysis was performed using the LaVision commercial software. The data was captured using a subset size of 31 pixels, a step size of 10 pixels, and the displacement field was calculated with reference to the initial, undeformed image. The data extracted from the experiments were the force values from the load cell and the corresponding displacement field measured by DIC. Two experiments were carried out for each angle.
