Abstract
This study investigates the cyclic plasticity of AZ31B extrusion under axial and shear loading conditions and presents a continuum-based cyclic plasticity model for the anisotropic behaviour of magnesium. An anisotropic form of the Armstrong-Frederick plasticity model is presented. It is shown that the model can independently produce hysteresis loops under pure axial and pure shear loading conditions. Two different parameters for loading and unloading were considered to address the asymmetric shape of the axial hysteresis loops. The model is evaluated by considering the cyclic stress-strain response of AZ31B extrusion in uniaxial and multiaxial loading cases. Stress amplitude, plastic energy and total energy densities are calculated using the proposed model and are compared with experimental results showing a good agreement.

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
