Abstract
We study the delamination of a compressed thin film from a solid substrate with continuum elasticity theory. Our model enables one to describe the advance of an undulated blister. It is shown that an elastic tension between the inner fold and the boundary of a blister is at the origin of the undulations. In addition, the essential experimental observations and recent simulations are reproduced very well: (i) Above a strain threshold, straight blister growth is unstable and starts to undulate. (ii) It is found that the period of the undulations scales with epsilon(*-1/2), where epsilon(*) is the isotropic compressive strain of the film. (iii) Similar periodic corrections to this power law scaling are recovered and are found to be associated with a growth instability.

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
