A new approach for Hugoniot equation of state of polycarbonate

摘要: Abstract The plate impact experiment is an important way to measure the equation of state solid material in high pressure. However, traditional methods always have some defects, such as failure rate, indefinite and inaccurate result test, lack comparison. Meanwhile, few published data concerned strain rate behavior polycarbonate during shock loading. In present study, a new approach was therefore carried out obtain single-stage gas gun, which consists asymmetric technology, manganin gauges, PVDF, electromagnetic particle velocity gauges electrical pins. least square method used analyze fitting goodness scatter degree single combined respectively. results showed that best property stability, followed by PVDF Compared with other method, can improve accuracy measurement relatively less number experiments than previous data. At last, D − u Hugoniot curve pressure gained, were calibrated experimental
