The use of in-material stress gauges for estimating the dynamic yield strength of shock-loaded solids

We present stress-time history measurements, with in-material manganin gauges, from which we obtain the dynamic yield strength of shock-loaded 2024 Al and Ti-6 Al-4 V specimens. This yield strength is inferred from the cusp in the release curve which results from the elastoplastic nature of the rele...

Zusammenfassung:We present stress-time history measurements, with in-material manganin gauges, from which we obtain the dynamic yield strength of shock-loaded 2024 Al and Ti-6 Al-4 V specimens. This yield strength is inferred from the cusp in the release curve which results from the elastoplastic nature of the release process. We show that while the strength of the aluminum alloy increases with shock amplitude, in the 0–100 kb range, that of the titanium alloy does not.
