Abstract
The stiffness properties of a finite sized square model element of an isotropic plate under plane stress are presented. The model is a piece of the material itself and not a configuration of bars that replace the material. It is shown that the use of an extra kinematic condition instead of an arbitrary displacement function usually produces better results. An example shows that this extra condition greatly increases the accuracy of the model and so reduces the number of degrees of freedom required to approximate the continuous system. A system of bounding the solution is shown by assigning values to free parameters. Thus the maximum error is known and can be reduced without going to a fine grid. The derivation of the isotropic square is then expanded to obtain the stiffness matrix of an elemental orthotropic rectangle. The limits of stability for both the isotropic and orthotropic models are investigated.

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
