PROJECT GOALS
1. Characterize properties of 3rd GEN 980 and 1180 MPa steels provided by the Steel
Marketing Development Institute (Blind Study)
2. Apply optimized fracture testing methodology established for Advanced High
Strength Steels (GDIS 2017 and GDIS 2018) to 3rd GEN Steels
3. Focus upon formability and fracture characterization of 3rd GEN Steels to integrate into
CAE toolkit from forming-to-crash (GDIS 2019)
4. Design forming process of full-size B-pillar for mid-size SUV using CAE toolkit with
Bowman Precision Tooling and Honda R&D (GDIS 2020)
5. Perform dynamic B-pillar impact tests to evaluate CAE toolkit and methodology to
design 3rd Gen. steel components from concept to crash the formed B-Pillar (GDIS 2020)
High-rate constitutive model to large strains and fracture locus for two 3rd GEN steels have been developed
Next steps:
• Transfer from coupon level testing to a structural component (B-Pillar)
• Experimental characterization for kinematic hardening to study springback
• B-pillar impact tests and CAE simulations from forming-to-crash
