Abstract
This paper describes how the yield stress of strong single crystals can be estimated from the Hugoniot elastic limit and the second- and third-order elastic constants. Data on germanium and silicon are analyzed. The dynamic yield stresses obtained are compared with a directly measured static value for silicon and for values obtained from Knoop hardness tests. The dynamic results for silicon and germanium are used along with a scaling law to estimate the yield stress for diamonds. This, in turn, is found to compare favorably with the values deduced from Knoop hardness tests and a directly measured static yield stress. The yield stress of diamond is approximately 35 GPa.This publication has 11 references indexed in Scilit:
