Abstract
To understand the various mechanisms of fiber deformation of flexible fiber suspensions, we carry out a direct simulation study to analyze the effect of fiber rigidity on fiber motion in simple shear flow. Such a study may be used to investigate the critical parameters controlling the breakage of flexible fibers during processing. We model the fiber as a series of rigid spheres connected by stiff springs. The stretching, bending, and torsional rigidities are determined by Young's modulus and shear modulus to realistically model the fiber rigidity. The model correctly predicts the orbit period of fiber rotation, T ̇γ, as well as the trend of critical flow strength, η ̇γ/E, versus fiber aspect ratio, r(p), at which breakage occurs in simple shear flow.

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
