Constitutive & Fracture/Modeling
The AHSS Constitutive & Fracture Modeling Team is developing and validating robust computer aided engineering (CAE) models for predicting fracture in AHSS / UHSS components. The Team’s primary focus includes the development of material test procedures to develop constitutive information for forming and fracture models with an emphasis on material anisotropy, accumulated work history, and nonlinear strain paths. The benefits of this project team 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.
