Fig. 1. Tensile test and DIC measurement system setup

Before the tensile test took place, calibration images were captured. A symmetric circular pattern was used, for compatibility with the VIC-3D software. Two image pairs were worked with: a reference pair from before the start of the test, and one after a small load had been applied. They are shown in Fig. 2.
