New Features in PolyUMod 6.4.1- Recompiled all Linux apps and library files using RHEL 7.9, instead of previous version which used RHEL 8.5.
- Improved how test cases are run.
New Features in MCalibration 6.6.0New Features- Improved how stress-strain predictions are stored in the mcal-file. The data is now stored in a more space efficient manner.
- Added a new load case type called "Graph Data". This load case type can be used to just Description experimental data.
- Added one more pre-defined virtual load case type: 10 tensile load cycles with increasing strain amplitude.
- Added support for the BAM hyperelastic material model in the PolyUMod PN model. This new model is EType=28.
- Added an internal solver for the Abaqus PRF model with 2 Yeoh hyperelastic networks, Bergstrom-Boyce flow, and isotropic hardening plasticity. This model is called "Abaqus-PRF2YB-Plast" in MCalibration.
- Added an internal solver for the Abaqus PRF model with 3 Yeoh hyperelastic networks, Power flow, and isotropic hardening plasticity. This model is called "Abaqus-PRF3YP-Plast" in MCalibration.
- Added internal solver support for Abaqus linear elastic with creep.
- Added internal solver support for Abaqus linear elastic with isotropic hardening plasticity and creep.
- Added one more predefined file size to the image export dialog.
- Added a fitness weight factor for load cases that do not finish.
- The virtual load case dialog now includes an experimental data library. It currently contains experimental data for: PET, ABS, and natural rubber.
- MCalibration now takes a field variable (which can be useful for analyzing material models that depend on, for example, humidity or moisture).
- The internal solver can now calibrate both WLF and Arrhenius time-temperature-superpositioning parameters for all relevant Abaqus material models.
Software Improvements- Improved the GUI interface for the Abaqus elastic-plastic material model with isotropic hardening.
- Can now specify that the number of pairs of stress-strain data should be determined from the experimental data.
- Simplified how the stress and strain types are specified for a load case.
- Switched to Qt 6.2.3 for the GUI toolkit.
- Improved how the MCalibration solver works with creep load cases.
- Removed support for the M8 material model.
- Improved the stability when reading in a mcal-file with issues.
- Improved the stability of the internal solver for the Abaqus Johnson-Cook plasticity model.
- Improved the Ansys elastic plastic with creep model.
- Removed "+" from exported LS-DYNA k-files.
- Load cases that use an Abaqus solver are now analyzed in separate subdirectories during calculations.
- In most cases MCalibration now automatically uses hybrid elements when needed.
- Cleaned up the material model selection dialog.
Bug Fixes- Fixed a bug in the Add Segment for a Virtual Load case dialog.
- Fixed a bug for large strain shear in compression.
- Fixed a bug in the save all calibration improvements to the model history function.
- Fixed a bug in the Ansys MISO Creep model.
The PolyUModlibrary is a library of advanced (and accurate) user-material models for finite element modeling of polymers, biomaterials, and other non-linear materials. Commercial finite element codes still lack the material models needed to accurately simulate many types of materials. Polymer FEM has developed a library of general purpose material models that cover virtually all polymer systems, including thermoplastics, thermosets, elastomers, foams, filled plastics, and biomaterials. The PolyUMod library also include specific models for particular formulations, such as fluoropolymers and UHMWPE.
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.
Complete Guide to Using MCalibration and PolyUMod with COMSOL MultiphysicsTutorial showing how to use a PolyUMod material models calibrated in MCalibration in COMSOL Multiphysics. The video shows all steps needed to setup, run, and analyze the FE results.PolymerFEM, LLCwas founded in 2020 by spinning off the software business from Veryst Engineering. The founder of PolymerFEM (Dr. Bergstrom) has extensive experience with non-linear finite element modeling and predicting material behaviors. The results from his work have been implemented into world-leading software for material model calibration (MCalibration), and a library of advanced material models (PolyUMod).
