Waves from a Suddenly Punched Hole in an Elastic Sheet Subjected to Finite Simple Tension
Bibliographic record
Abstract
We consider the plane stress unloading waves emanating from a suddenly punched circular hole in a thin elastic sheet, subjected to an initial finite deformation simple tension. The sheet is assumed to be hyperelastic, isotropic, incompressible and thin enough that the generalized plane stress approximation is valid. It is further assumed that the plugging of the hole is due to normal impact of a cylindrical projectile and that the impact velocity of the projectile is sufficiently high that the plugging can be assumed instantaneous. The governing equations of the problem are obtained in Lagrangian form with respect to a reference configuration that is the initial stretched configuration. A numerical scheme is proposed for the solution of the governing equations, and numerical results are obtained for the neo-Hookean strain energy function. However with some additional complication other isotropic strain energy functions can be considered.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
