In order to ensure consistency and comparability, the test procedure for this study was designed to closely replicate the steps outlined in reference [1]. All aspects of the testing process, including the preparation, setup, and execution, were meticulously followed according to the guidelines provided in the reference. 3. Results and discussion The fractures of all PRTS specimens were observed on the side where the camera was recording, as depicted in Fig-ure 4. The average break force value for all PRTS specimens is 16686.4 N, along with average standard deviation of 4404.68N.

According to the experimental data shown in Figure 5b, the D block junction's area of interest saw the highest strain values. In Figures 5b, the apex (yellow line) represents the greatest von Mises values, which were 45%. The von Mises strain is depicted as a function of time for four stage points in the diagrams in Figures 5c. Similar trends can be seen in the stage point diagram (Figure 5c), which is consistent from the first to the tenth stage. However, the strain values exponentially rise from the tenth stage to the fracture, with a maximum von Mises strain of 45%.

Fig. 5 The von Mises strain field for S3 PRTS was visualized prior to fracture, as illustrated in Figure (a). Figure (b) represents the distri-bution of von Mises strain values along the section length. Additionally, Figure (c) shows the variation of von Mises strain values over time.

The diagrams in Figure 6 show average strain-stage dependence with standard deviation values for all PRTS.
