In order to investigate the glass strength subjected shock tube loading, characteristics of the shock wave pressure generated in a vertical shock tube with 300mm×300mm square and an enhanced stress measurement technique of 100kHz frequency have been studied. Value of shock wave loading to glass specimen could be estimated from that of pressure behind the reflected shock wave measured by the pressure transducers mounted at the sidewall of the shock tube. Radical increase and monotonic decay were observed in the recorded profile of the shock wave, and generated stress could be measured with a high accuracy.
