Query: Experimental results and constitutive modelling for tungsten and
  tantalum at high strain rates and very high temperatures   Recently reported results of the high strain rates, high temperature
measurements of the yield stress of tungsten and tantalum have been analyzed.
The highest temperature reached in the experiment, based on heating and
stressing a thin wire by a fast, high current pulse, was 2520 K and 2720 K, for
tantalum and tungsten, respectively. The strain-rates in both the tungsten and
tantalum tests were in the range from 500 to 1500 1/s. The parameters for the
constitutive equation developed by Zerilli and Armstrong have been determined
from the experimental data and the results have been compared with the data
obtained at lower temperatures.
