Material Model Calibration


  • MCalibration - Fast and Powerful Material Model Calibration Tool

    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™. This 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. Contact Dr. Jorgen Bergstrom if you would like a quotation for the software.

    The following are some of the key features of MCalibration:
    • Is available for both Windows and Linux computers.
    • Can extract material parameters for the all material models in the PolyUMod library. The PolyUMod library is available for Abaqus, ANSYS, and LS-DYNA.
    • Can extract the material parameters for many common hyperelastic and metal plasticity models.
    • Can extract the material parameters for all built-in material models in Abaqus and ANSYS.
    • The optimal set of material parameters can be exported into text files that can be directly read by Abaqus, ANSYS, and LS-DYNA.
    • The parameter extraction is more powerful than the built-in features of Abaqus and ANSYS in that it allows for multiple experimental test with different weight functions.
    • Can calibrate viscoelastic, viscoplastic, and anistropic material models.
    • Can quickly check the stability of any supported material model.
    • Can perform virtual experiments in different loading modes, and different stress or strain histories.
    • The calibration can be performed on a subset of the material parameters, and parameters can have upper and lower bounds.
    • Most material models can be calibrated without any call to Abaqus or ANSYS. MCalibration do not require that a FE program is installed on the computer.

    The Case Studies section give examples of how MCalibration can be used as a parameter extraction tool. Here are some of the available case studies:
