The pressure dependence of the yield strength of shock-loaded Manganin gauges

The variation of the yield strength with shock pressure of Manganin foil gauges can be determined by analyzing their dynamic calibration curve.

Zusammenfassung:	The variation of the yield strength with shock pressure of Manganin foil gauges can be determined by analyzing their dynamic calibration curve. The analysis is based on the assumption that the material behaves as an elastoplastic work-hardening solid and on the general expression for the resistance change of Manganin which we derived in previous works. It is found that the strength increases by a factor of about 3.5 for shock stresses in the range of 0–160 kbar.
