Abstract

Previous results of plane shock wave experiments on soda lime glass do not show a sharp unambiguous cusp in its wave profiles indicating the limit of elastic deformation i.e., Hugoniot Elastic Limit (HEL). This research was initiated to determine whether the effect of the change in the refractive index of the glass on the shift in Doppler frequency can be used to determine its HEL under shock compression. Based on the results of a limited number of experiments performed on soda lime glass, it is inferred that the HEL of soda lime glass is 3.10 ± 0.06 GPa. 1 Introduction In the range of stress where finite strength of a solid influences the deformation mode of the material it is useful to know the stress to which it deforms elastically.
