Experimental Study of Glass Strength against Shock Wave Loading-Shock Wave Properties and Method for Stress Measurement-

摘要

In order to investigate the glass strength subjected shock tube loading,characteristics of the shock wave pressure generated in a vertical shock with 300 mmX300 mm square and an enhanced stress measurement technique to 100 kHz frequency have been studied.Value of shock were 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.
