    Meeting todays's material data needs

    In order to be able to support our customers with the provision of high-quality accurate data, representative of everyday production, Tata Steel has created Aurora® Online: a single and consistent source of material engineering data for entire portfolio of steels.

     

    • Save time in simulating

      Aurora® Online aims to provide data sets that depict the actual steel properties, and not simply the specification limits. Making all this data available in easy-to-read Excel datasheets and in ready-to-run input deck format, customers no longer need to fit Yield Loci, Forming Limit Curve and Hardening Curves themselves.

      Therefore this powerful tool will save you hours in setting up accurate, reliable simulations.

       

       

       

    • High accuracy: Vegter 2017

      Vegter 2017 is a new method to predict an advanced yield locus using the tensile properties in 0°, 45° and 90°. You're able to achieve the most accurate simulation result, with a minimal amount of experimental input data:

      • no need for special tests

      • as easy as Hill’48, but much more accurate

      FE suppliers AutoForm, LS-Dyna (Dynamore) and PAM-Stamp (ESI) have implemented Vegter 2017 in their software.

    Overview

    Aurora® Online is an additional service to our customers, giving a fast and easy electronic access to material data for an improved understanding of our materials portfolio and performance. The database offers basic material data (standard mechanical properties), as well as advanced material data required for computational engineering methods, such as finite element methodology. All data is available in easy-to-read Excel datasheets and in so-called ready-to-run input deck format (for the most commonly used FEA packages). 

    What makes Aurora special is the feed with advanced material data and plasticity models developed by the Tata Steel’s Product Application Center. This center is recognized for its world-leading expertise on material plasticity. This knowledge and expertise forms the basis for Aurora online and allows you to set up accurate and reliable forming and crash simulations that reduce lead times and expenditure during the development of new vehicles and tools.

    R2R input deck

    A special feature of Aurora Online are the Ready-to-run (R2R) input decks. These material files contain all required material data on a specific grade and can be directly used within CAE software to run forming and crashworthiness simulations. Support is currently available for ABAQUS, AutoForm, LS-DYNA, RADIOSS and PAM-STAMP/PAMCRASH.
