Fig. 3. The load-time and temperature-time curves for the specimen with the rhomb-shaped notch and the corresponding evolution of the region with the active plastic deformation.

Fig. 4. Evolution of the inhomogeneous strain rate fields on the surface of the specimen with the rhomb-shaped notch during uniaxial tension.

In the performed experi mental pictures, the numbers 1‒6 corresponds to the characteristic patterns of the strain fields. We can specify five stages of the active plastic deformation based on the matching the DIC results and the
