Figure 6
Representative stress–strain curve from the 1100-O aluminium samples pulled in tension. The current data, representing a testing strain-rate of 5000 s−1, is demarcated with the solid black curve, and for comparison previous data performed at 1000 s−1 (Kahn & Huang, 1992; Lindholm & Yeakley, 1968) have also been included. The various symbols which are overlaid on the plot dictate stress–strain states at which a diffraction pattern has been recorded with the ICCD. In-depth analysis from only an unloaded sample and a sample loaded up to demarcation 10 have been included in the in-depth diffraction pattern analysis shown in Fig. 8, as the current goal of this study is to show the possibility of performing such high-strain-rate loading while simultaneously capturing high-frame-rate diffraction patterns and phase-contrast images. |
