摘要
Abstract
Symmetric plate impact experiments were performed using a two-stage light gas gun to investigate the dynamic response and optical properties of polymethylmethacrylate (PMMA)under shock loading.The particle velocity of the flyer/sample interface,the shock velocity,and the refractive index of the sample were measured using a Doppler pin system (DPS).The measurements produced accurate Hugoniot data for PMMA,with the uncertainty of the shock velocity below 1%.The velocity correction at 1550 nm of the wavelength under shock pressures ranging from 6 to 50 GPa was also obtained.The relationship between the refractive index and the density under shock compression was deduced from the measurements.Moreover,the shock velocity was distinctly captured by DPS and its relationship with the actual shock velocity was examined.关键词
