Abstract
The recently developed large strain elastic visco‐plastic self‐consistent (EVPSC) model, with various popular self‐consistent schemes including the Affine, Meff, Secant, and Tangent, is used to study the lattice strain evolution in a stainless steel under uniaxial tension. The material parameters for the various self‐consistent schemes are fitted to experimental stress and strain curve under uniaxial tension. An assessment of the predictive capability of the self‐consistent schemes is performed based on comparisons of the predicted lattice strain evolutions and in situ neutron diffraction measurements done on the same material. It is found that, among the self‐consistent schemes examined, the self‐consistent schemes with grain interaction stiffness halfway between those of the limiting Secant (stiff) and Tangent (compliant) approximations give the best results.

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 it
