More accurate simulations for smoother tool try out and testing
Aurora Online offers our customers on-demand access to representative material data and advanced material models to predict and enable accurate simulations for reduced tool try-out time and no surprises during crash testing. Using advanced material data and plasticity models and with the support of our world leading R&D experts on material plasticity, you can set up accurate and reliable forming and crash simulations that reduce lead times and lower expenditure on materials testing during the development of new vehicles and tooling.
Aurora Online provides data sets that depict the actual steel properties, and not simply the specification limits. With all data available in easy-to-read Excel data sheets and in ready-to-run input deck format, customers no longer need to fit yield loci, forming limit curves and hardening curves themselves.
That's how this powerful tool will save you hours in setting up accurate, reliable simulations. The ready-to-run input decks are available for the most commonly-used forming software packages including:
- PAMSTAMP (ESI Group)
- PAMCRASH (ESI Group)
- Stampack Xpress
- MSC Marc
- Mentat/Simufact Forming
Instant access to material data when you need it for material assessment
The Aurora Online database is instantly and easily accessible, ensuring accurate and consistent data whenever you want it, without having to call suppliers or test samples, making it ideal for urgent requests. It also offers access to the most up-to-date material data and information on new grades for the early evaluation of new materials.
Highly accurate advanced material models
Accurate simulations are not only about high quality data, but also realistic material models. Tata Steel's R&D has experts dedicated to the development of representative material models for all material types. Examples include:
- Vegter 2017 Yield Locus: a new method for predicting advanced yield criteria input parameters from tensile properties
- Abspoel & Scholting Forming Limit Curve: an efficient and reliable method for predicting forming limit curves from tensile properties in 0°, 45° and 90°
Aurora Online contains both input data and ready-to-run decks to facilitate easy use of these models. You can achieve the most accurate simulation result with a minimal amount of experimental input data:
- no need for special tests (biaxial, plane strain and shear stress points)
- as easy as Hill’48 and Keeler, but much more accurate
FEA suppliers AutoForm, LS-DYNA, MSC Marc and Mentat, PAM-CRASH (ESI Group), PAM-STAMP (ESI Group) and Stampack Xpress have implemented Vegter (2017) in their software allowing you to use the same material models globally. The Abspoel & Scholting Forming Limit Curve is implemented in AutoForm. For other packages the data can be imported as tabulated data.
Tata Steel offers Aurora Online to its valued customers to support fast evaluation of new products, to access advanced material cards for accurate simulations and to enable joint simulation projects.
