3. Practical determination of rheological parameters
The coefficients characterizing a material's sensitivity to strain rate or temperature, as well as the parameters for quantifying work hardening and dynamic recovery, are defined in the files and . They can all be determined from stress-strain curves obtained from tests carried out at different strain rates and temperatures.
3.1 Sensitivity to strain rate (m)
This parameter is defined by the partial derivative :
