Specimens were cut from a sheet of aluminium alloy 6082- T6. Figure 4 : Typical image collected from the experiment at a load of 1:25 kN. Sets of points are selected on either side of the crack to measure displacements. Figure 5 : Series of images aligned to give an image of the full crack length at a load of 1:25 kN
