Working with any material model requires defining appropriate material parameters from experimental data. This can be challenging when the advanced material model is non-linear. To facilitate parameter extraction,
Veryst Engineering has developed MCalibration™. The software enables semi-automatic extraction of pertinent material parameters from experimental data. This application is provided with the PolyUMod user-material libraries, but is also commercially available through a stand-alone license.
The following two examples illustrate the use of the MCalibration parameter extraction tool.

Shift Functions and Reduced Time
Hi, .
shriisall 2010-09-07 14:31For thermorehelogically simple materials in viscoelasticity, we know that the use of shift functions to calculate relaxation times (tau) at different temperatures
tau(T) = tau(Tref)A(T) ...
