“…We have collected experimental measurements of the spall strength for Al and its alloys from the literature [13][14][15][16][17][18][19][20][21][22][23]. Figure 2 shows the normalized critical velocity as a function of the normalized spall strength following Eq.…”

“…The procedure of the optimization of the SRS for the VISAR mentioned here is successfully implemented and the parameters of the SRS in all shock experiment are selected on the basis of the above-mentioned results. The mechanical and physical properties of the materials have successfully been estimated from the free surface velocity history derived using the recorded fringe pattern [15,24]. This generic procedure of identifying the suitable operating range of the SRS for a VISAR interferometer could be utilized for similar setups with different optical components and photodetectors.…”

“…, is shown. Here, fracture data relative to axisymmetric smooth and notched bar specimens were taken from [36] while fracture strain at the onset spall was determined using experimental data reported by Joshi, et al [39]. The value of the stress triaxiality at the onset of spall fracture was found about 4.…”
