Abstract
In the past two decades, the active and controllable mechanical properties of piezoelectric materials and shape memory alloys have been widely employed in structural enhancement and repair with remarkable and interesting research findings. This article is designed to introduce and review these research findings. The active electromechanical property of piezoelectric materials is presented first. The research findings on both structural stability enhancement of engineering structures and repair of cracked/notched and delaminated structures under static and dynamic loadings via the piezoelectric materials follow. The active thermo-mechanical property of shape memory alloys and their applications in structural enhancement and repair are also briefly presented. Limitations of the current studies and recommended future endeavors are summarized as well. This review sums up different methodologies and designs in structural enhancement and repair using piezoelectric materials and shape memory alloys to promote new applications in the area.

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
