Crystal Plasticity Based Transformation Induced Plasticity Formulation for Predictions of Forming Limit Diagrams
Bibliographic record
Abstract
Significant effort has been invested into the development and research of Advanced High Strength Steel. In particular, transformation induced plasticity (TRIP) steel has shown promise as a candidate for lightweighting of vehicles because of their enhanced formability. However, predictive modeling of TRIP steel in formability is difficult due the combination of dislocation and transformation mechanisms occurring during deformation for various strain paths. This work presents a crystal plasticity constitutive model to simulate the behaviour of deformation induced γ → α' transformation. A physics based transformation model is implemented into the crystal plasticity framework to fully capture the behavior of TRIP assisted steels. Simulations are calibrated and compared to experimental measurements of Duplex Stainless Steel. The calibrated model is then used to predict the forming limit diagram using the Marciniak-Kuczynski approach. The results highlight the importance of a physics based used in simulation to fully utilize TRIP assisted steels.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
