Veryst Engineering PolyUMod 4.6.0

Veryst Engineering has released 4.6 version of PolyUMod is a library of advanced (and accurate) user-material models for finite element modeling of polymers, biomaterials, and other non-linear materials.

v4.6.0 (Released 2017-10-05)

- PolyUMod: Implemented support for a library of already calibrated material models. This release supports already calibrated material models for: PTFE, PET, and HDPE.
- PolyUMod: Now works with MSC.Marc 2017, ANSYS 18.2, and COMSOL 5.3a.
- PolyUMod: Started to add a new anisotropic viscoplastic material model that supports volumetric flow.
- PolyUMod: Added a new flow model to the Parallel Network (PN) model. The new flow model (FType=519) is called Power-Law Flow with Volumetric Dilatation.
- PolyUMod: Added a new elastic element type to the Parallel Network (PN) model. The new elastic element type (EType=26) is called Eight-Chain Hyperelastic Model with Strain-Dependent Modulus.
- PolyUMod: Added a new two-network anisotropic viscoplastic material model for thermoplastic materials. The new material model is called the A2N model.
- PolyUMod: Almost all material models now consider initial stresses. In Abaqus, the initial stresses can be specified with the *INITIAL CONDITIONS, TYPE=STRESS command.
- PolyUMod: The Multi-Rate, Multi-Temperature, and Time-Switch model frameworks now work with all supported FE solvers.
- PolyUMod: The DNF model can now use etaVol=0 to deactivate volumetric flow, and thetaBase=0 to deactivate pressure dependence.
- PolyUMod: Fixed a bug in Parallel Network (PN) model flow element FTYPE=508.
License Server: Switched to rlm version 12.2.
- MCalibration: Made it faster to activate and deactivate load cases, and to move load cases in the load case table.
- MCalibration: Updated to Qt 5.9.1 for Windows.
- MCalibration: The material parameter's table is now disabled during calibrations.
- MCalibration: The Compression with Friction load case now also works in tension. In this case the top and bottom surfaces are tied.
- MCalibration: Load case tool tips are now truncated if more than 30 lines long.
- MCalibration: The mcal-file now saves more settings of the main graph.
- MCalibration: Removed qtwebengine, making it easier to deploy the software.
- MCalibration: Fixed a bug that prevented the Poisson's ratio from being plotted properly if the first two experimental data points have zero axial strain.
- MCalibration: Virtual load cases now work better when using stress control.
- MCalibration: Fixed a bug in the Abaqus-Hyperelastic-Mullins model.
- MCalibration: Made the Levenberg-Marquardt optimization algorithm more robust.
- MCalibration: The Abaqus Hyperelastic-Yeoh-Mullins model is now imported properly from an Abaqus inp-file.
- MCalibration: Added flag in the load case dialog box for specifying that an LS-DYNA simulation should use quasi-static control.
- MCalibration: Can now set the time step size for multiple load cases at once.


About PolyUMod. Veryst Engineering offers the PolyUMod Library of user-material models for non-linear finite element modeling of engineering polymers and biomaterials. This library provides numerically efficient material models that can be used to very accurately represent the large strain viscoplastic response of materials. The PolyUMod library contains general purpose material models that cover virtually all polymer systems, including thermoplastics, thermosets, elastomers, foams, filled plastics, and biomaterials. Specific models have also been developed for particular formulations such as fluoropolymers, PLA, and UHMWPE. The Veryst material model library contains more than 20 material models.

Veryst Engineering has also developed the MCalibration parameter extraction software that makes it easy to calibrate any PolyUMod or Abaqus, ANSYS, LS-DYNA, and other FE software. native material model. The calibration software allows the user to analyze a set of experimental data files in order to determine the optimal model parameters.
