Constitutive & Fracture/Modeling

AHSS Constitutive & Fracture Modeling is developing and validating robust computer aided engineering (CAE) models for predicting fracture in AHSS / UHSS.  The benefits of this project will be the continued use of newer grades of AHSS / UHSS to meet safety and crashworthiness performance targets while still achieving the desired mass reduction, a recommended approach to CAE simulation, prediction of fracture failure under crash loads, and the establishment of material / part design / part processing recommended practices to ensure robust performance under crash loads.
