Which Ansys Creep Model is Best?
Review of different creep models that are available in Ansys Mechanical. In the article I will recommend which to use and which to avoid.
PolymerFEM 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.
PolymerFEM has also developed the MCalibration® parameter extraction software that makes it easy to calibrate all PolyUMod material models and all Ansys Mechanical material models. The calibration software allows the user to analyze a set of experimental data files in order to determine the optimal model parameters. The typical workflow includes: (1) Import all relevant experimental data. This includes test data from tension, compression, shear, biaxial, and plane strain tests, as well as DMA data, dogbone-shaped tension tests, compression tests with friction, stress relaxation, creep, permanent set, Poisson’s ratio, and fatigue data. (2) Select one material model that should be calibrated to the complete set of experimental data. (3) Run the calibration using a fully automatic calibration algorithm.
The MCalibration software can calibrate both isotropic and anisotropic material models, and can also calibrate temperature-dependent material models. After the material model calibration has been completed the results can be exported to Ansys APDL or Engineering Data xml-format
