Failure Characterization of Multi-Alloy and Multi-Gauge Hot-Stamped Tailor-Welded Blanks
Bibliographic record
Abstract
To increase the ductility of hot-stamped structural components, the use of tailor-welded blanks (TWBs) of both high-strength and ductile steels has recently drawn attention. In this study, the failure behavior of the hot-stamped tailor-welded blanks (TWBs) comprising steel sheets of Ductibor®500-AS laser-welded to Usibor®1500-AS was investigated. TWBs with different combinations of 1.2 mm- and 1.6 mm-thick parent metals were hot-stamped and then tested under uniaxial-tension and equi-biaxial-tension loading conditions. Under longitudinal uniaxial-tension loading, all of the TWB types failed in the Usibor®1500-AS whereas in transverse uniaxial-tension loading, the failure occurred in the Ductibor®500-AS. Furthermore, in the equi-biaxial-tension tests, the 1.2 mm-1.6 mm TWBs presented the highest strains prior to failure, while fracturing in the Ductibor®500-AS sheet.

How this classification was reachedexpand
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.
