Welcome to MCalibration

Calibrating a material model is difficult, and the accuracy of your FE model strongly depends on how accurate your material model is. At PolymerFEM we have developed MCalibration®, the best material model selection and calibration tool available! MCalibration makes it easy to find the best material models for your materials.

Material Model Calibration

Working with any material model requires determining appropriate material parameters from experimental data. This can be challenging when the advanced material model is non-linear. To facilitate the parameter extraction, Polymer FEM has developed MCalibration. This software application enables semi-automatic extraction of pertinent material parameters from experimental data. The MCalibration application is provided with the PolyUMod user-material libraries, but is also commercially available through a stand-alone license. Contact us if you would like a quotation
for the software.

The MCalibration application can extract the material parameters for all native material models in Abaqus and ANSYS, and all material models in the PolyUMod library.

Here are some of the key features of MCalibration:

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

Experimental Testing

In order to run an FE simulation it is necessary to specify three types of input:

1

The geometry of the part.

2

The load and boundary conditions.

3

The material behaviors.

Often the most difficult of these is the specification of the material behavior, especially for highly non-linear materials, such as polymers.

The specification of a material behavior requires a suitable material model calibrated using the right type of accurate experimental data.

Getting the right type of experimental data that is relevant, accurate, and completely specifies the material response is a necessary input to the material model calibration. It is not trivial to determine what experiments should be performed, and it is not trivial to run the experiments in a proper way. In our test lab we have developed “smart” testing programs for all types of engineering polymers (elastomers, thermoplastics, and thermosets). These testing programs are unique in that they obtain the necessary information for advanced material model calibration using a small set of experimental tests.
