Schematic illustration of charged and discharged system and current measurement of discharge circuit through the Rogowski coil.
The current response of copper wire recorded by Rogowski coil, which is captured by a digital oscilloscope. The inflexed site of plasma formation denotes the initiation of explosion.
Schematic arrangement for expanding ring experiment imposed by wire explosion of the exploding wire.
Expansion velocity-time history of two PETN diameters: (a) 10 mm; (b) 12 mm, each of which has three independent tests.
The stress-strain response of OFE copper determined from the data in Fig. 4 and numerically obtained using Johnson-Cook model. The dot line represents the SHPB result at a strain rate of 5000 s−1.
(a) Experimental setup of seven aluminium rings; (b) reassembled fragments for different rings.
The complementary cumulative distribution of fragment number as a function of fragment size. The dashed line denotes the Weibull fit of the experimental data.
Dimensions of test rings and PETN and PETN mass.
