Abstract

fetched live from OpenAlex

A pseudo-elastic constitutive equation describing the mechanical properties of bovine myocardium was developed. The myocardium was modeled as a hyperelastic transversely isotropic material with a minimum viscoelastic loses. The material parameters for the proposed constitutive equations were determined using GA regression technique. In this work, the development of a constitutive equation based on principal stretch ratios is explained. The predictive capability of proposed model was compared against the experimental data obtained from part one. Finally, the constitutive equations were implemented into a commercial finite element program and the results of the mathematical model and FEM were compared with the experimental data.

Teacher imitation

Not 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.
