Definitions and Methods for Worst Case Materials in Formability Simulations 2012-01-0017
Two types of approaches for material definitions and methods for worst case scenarios are explored. The first is from the material specification supplied by the OEM or the alloy producer for the material, which has basic material properties and no specific FLC. The potential exists that any material within the specification can be delivered to the stamping plants. The second is if the material is to be supplied within a narrowed band of material specification with a known FLC. For both cases, there is considerable pressure from product design to use the most formable material possible. However, if a material is delivered outside the FEA testing limits, the results can be catastrophic. A specification is proposed to take advantage of the formability capability to enhance product performance while minimizing stamping plant risk.
