The Dynamic Response of Oxynitride Glass.
Abstract
Plate impact experiments were performed on two grades of oxynitride glass. Material manganin guages were used to determine the dynamic response of this material in the range of 0 to 12 GPa. In the high stress range the measured stress signals showed that the transmitted waves are composed of an initial elastic jump followed by stress relaxation and a subsequent 'plastic' wave. The 'plastic' transition occured at 9.0 + or - 0.2 GPa for a 6.0 at % nitrogen glass and at 10.4 + or - 0.3 GPa for a 3.3 at % nitrogen glass. This behaviour is characteristic of ductile metals, but is seldom observed in glasses. The Hugoniot curves for both the above nitrogen compositions were determined in the range of 0 to 1 GPa and their spall strength in this pressure regime was estimated from the manganin guage record.
