Abstract
The potential of piezoelectric ceramics on repair of delaminated structures subjected to a static loading is researched in the letter. A sliding fracture mode on two tips of a delaminated beam structure was uncovered by the author in a previous report. The stress singularity due to the fracture mode at the tips is attempted to be mended with a pair of piezoelectric patches by virtue of their electro-mechanical characteristics. A developed mechanics model is employed to study the applicability of the piezoelectric materials in repairing four types of delaminated structures, i.e. simply supported, cantilevered, propped cantilevered, and fixed beams. The effectiveness of the proposed method is particularly investigated with respect to the locations of the delamination in both the thickness and longitudinal directions of the beams. It is hoped that the research findings in the letter will promote an application of smart materials to repair delaminated or cracked engineering structures.

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
