.. _auto_metalforming_material_database:

*PROVIDES A DATASET OF MATERIALS BASED ON COUNTRY AND MATERIAL TYPE*
====================================================================

Queries the metal-forming material database and returns a consolidated LS-DYNA keyword file containing all calibrated material cards that match the selected country and LS-DYNA material type. Use this worker to retrieve ready-to-use MAT_001/018/024/036/037 definitions for stamping and forming simulations without manual library searches.

When to use
-----------

Tagged: ``forming``, ``keyword``, ``library``, ``lsdyna``, ``mat_18``, ``mat_24``, ``material_database``, ``metal_forming``.
