PolyUMod Overview

In many important applications the material response is sufficiently non-linear that simple hyperelasticity or metal plasticity is not good enough. In these cases the PolyUMod library can be very useful since it contains a selection of the most advanced and accurate material models that are currently available. The PolyUMod library is easy to use and can give you a significant competitive advantage!

MCalibration

Selecting and calibrating a suitable material model can be very challenging. The MCalibration software makes that task easy! It can calibrate all PolyUMod material models, and most built-in models in FE solvers.

Advanced plotting capabilities tailored for model predictions

Guesses for all material parameters are provided

Experimental data files can be loaded by drag-and-drop

Multiple material models can be calibrated to the same experimental data

Contains a number of already calibrated material models for common polymers

Detailed information about non-linear modeling is given in Dr. Bergstrom's book

Should Material Model Parameters be Unique?

Jorgen 2022-12-23

If you repeat a material model calibration multiple times, should you expect the optimal material parameters to be unique?

MCalibration is my go-to software for material calibration and I don't see any other software that is even close to it.

MCalibration is essential to do quality material model development. It is simple, it is well documented and the tech support is top notch.

It's by far the best tool we have identified to give us detailed material data for non-linear materials for our complex multi-physics FEM modelling.

Major use of MCalibration in R&D projects with industrial partners.

The best part for me as a researcher is, that it is very clear which models are implemented and how. Also, I really like the fact that there is an active community online (the forum), in which discussion is not limited to software specific issues as is the case with most commercial software, but rather very general polymer mechanics related.

The software is easy to use, very fast, possible to connect to external solvers, virtual testing and exploration of material models.

Put simply, MCalibration and PolyUMod have enabled us to develop the constitutive models and perform the FEM analysis that we need to do, and to do so in-house.

The examples help identify the basic underlying principals of material modeling and calibration.

MCalibration is easy to use. The tutorials and manual are useful in providing the overview of information while including specifics on material model parameters and applications.

MCalibration and PolyUMod are easy to use and useful for someone who is working on material behavior.

If I had to rank what was most valuable, I think the very top of the list are the quick start mini guides that you had embedded in MCalibration that cover things like additional history solver variables and the basic calibration topics.

MCalibration is a really convenient and useful program.
