Abstract
An innovative wedge-anchor system with a longitudinal circular profile has been designed for gripping carbon-fiber-reinforced-polymer rods. The anchor system, consisting of a barrel, a number of wedges, and a sleeve, is capable of carrying the ultimate tensile strength of the rod. Three-dimensional (3D) and axisymmetric finite-element models have been developed and applied in order to determine the stresses inside the anchor system. Using the 3D model, the overall performance of the anchor represented by the tensile load-displacement relationship compared favorably with the experimental results. A comparison study between the 3D and axisymmetric models revealed that the axisymmetric model underestimated the contact pressure on the rod surface. Using the force-fitting principle of thick cylinders, a mathematical model was also developed, and under specific assumptions, the mathematical solution compared favorably with finite-element model 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
