Tensile tests were carried out on long aluminum wires (360 mm) at room temperature using a Schenck Trebel RMC100 universal electromechanical machine with a force of 100 kN. Figure 2 shows the stress-strain curves for aluminum. According to the results obtained, the yield strength of aluminum was determined to be 55 MPa. Based on this value, the tensile stress in the experiment was selected. A detailed description of the setup and methodology of the experiment is given in our previous study (Dmitriev et al., 2024).
