The Extended Peel Zone Model: Effect of Peeling Velocity
Bibliographic record
Abstract
According to the peel zone model proposed by Pesika et al. [8 Pesika , N. S. , Tian , Y. , Zhao , B. , Rosenberg , K. , Zeng , H. , McGuiggan , P. , Autumn , K. , and Israelachvili , J. N. , J. Adhes. 83 , 383 – 401 ( 2007 ).[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]], the peel strength of an adhesive tape is proportional to the length of the peel zone or the bifurcation region at the peeling front between the tape backing and the substrate. In this study, the effects of the peel angle and peel velocity on the shape of the peel zone and the peel strength are further investigated theoretically and experimentally. The theoretical analysis on the angle at the edge of the peel zone, θ0, and the peel strengths at different peel velocities and angles was compared with experimental tests using three different commercial tapes. The experimental results are in good agreement with the extended peel zone model, which provides a simple approach to predict the peel strength of adhesive tapes with different physical properties at different peel angles and velocities.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
