shows loading diagrams obtained from the data of the built-in sensor of the testing machine, and by using the additional software module of the video system ‘ virtual extensometer ’ . For points 1 – 6 (Fig. 3) the transverse (Fig. 4, Fig. 8), longitudinal (Fig. 5, Fig. 9) and shear strain fields (Fig. 6, Fig. 10) are shown.
