Sheet Steels

Updates to the Sheet Steels data tables, part of the Advanced Materials - Metals data bundle.

A property data resource containing information on over 130 grades of sheet steels commonly used in the automotive and manufacturing industries, and collated from multiple sources:

  • The StahlDat Sheet Steels dataset originally developed by the German Steel Institute and a consortium of automotive OEMs and steel producers. This data is compiled by Matplus GmbH and licensed for distribution by ANSYS, Inc. Summary datasheets are provided in the Sheet Steels Design Data section. These contain mechanical and processing information and are linked to underlying raw test data in the Sheet Steels Test Data section.
  • Data calibration on selected datasheets was carried out by DYNAmore (an Ansys company) in accordance with voestalpine Stahl GmbH and applicable international standards to transform raw test data into simulation-ready format. These datasheets are included in the Sheet Steels Design Data section.
Note: ANSYS, Inc. provides no warranty for this data.
  • Sheet Steels Design Data - Data compiled from multiple sources and licensed for distribution by ANSYS, Inc.
  • Sheet Steels Test Data - Data compiled by Matplus GmbH and licensed for distribution by ANSYS, Inc.
Crashworthiness simulations
This release introduces comprehensive support for advanced crashworthiness simulations, featuring:
  • Rate-dependent plasticity data covering strain rates from 0.0001/s to 1000/s.
  • Stress-state-dependent damage modeling including GISSMO damage model parameters.
These enhancements apply to nine automotive-grade sheet steels, comprising:
  • High-strength low alloy (HSLA) steels
  • Complex-phase (CP) steels
  • Dual-phase (DP) steels

All grades are manufactured and supplied by voestalpine GmbH and are widely used across industries including automotive, construction, energy, rail, and consumer goods.

Simulation-ready data access
  • Design Data Table - Contains calibrated material data for the 9 materials, ready for export to LS-DYNA material cards. Calibration has been performed by DYNAmore Material Competence Center.
    • MAT_24 can be exported with rate-dependent flow curves.
    • MAT_ADD_DAMAGE_GISSMO can be included to represent stress-state dependent damage using the GISSMO model.
  • Test Data Table - Hosts the underlying experimental data, including three new test types specifically supporting GISSMO calibration:
    • Notched tensile tests
    • Notched shear (0 and 45 degrees) tests
    • Punch tests
  • Data linkage and consistency:
    • Each record in the Design Data table is linked to its corresponding test data in the Test Data table.
    • Folder and record formats in the Test Data table have been updated to align with the Design Data table, ensuring consistency and ease of navigation.
New Ansys Forming exporter

This release adds the capability to export sheet metal (LSM) materials with forming curve data to JSON format material cards that can be imported into Ansys Forming, the dedicated simulation solution for stamping and sheet metal forming.
