Abstract
Wrinkles in composite structure have been a source of concern since the first structural laminates were developed. Identified as out of plane distortions in the fibers of composite laminates, wrinkles are known to dramatically reduce laminate strength. To address these issues, an experimental investigation was undertaken to determine the critical characteristics of wrinkles as related to the static strength of composites. The critical characteristics include wrinkle type, wrinkle aspect ratio, and wrinkle depth. Resulting characterizations were used to determine design allowables for further analysis of discrepant parts. This work also investigated the interlaminar failure mechanisms of two types of wrinkles (outward and inward) and found static tension and inter-laminar tension are critical to failure initiation and propagation. Finite Element Modeling was used to show that numerical methods could predict these types of wrinkle-induced failure mechanisms.

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
