Experimental Assessment of Single and Cumulative Impact Damage in Carbon Fiber Polymer Matrix Composites Using Electrical Resistance Measurements
Bibliographic record
Abstract
In this work the impact damage sensing capabilities in AS4/3501-6 carbon fiber polymer matrix composites are investigated. A fully instrumented experimental setup for characterization of electrical properties has been developed. The one-dimensional electrical resistance method was employed for damage sensing. 16-ply [0/45/–45/90] 2s and 32-ply [0/45/–45/90] 4s laminates were tested. Single impact and cumulative low velocity impact studies were conducted and electrical resistance measurements were performed to assess damage. The results show that the one-dimensional electrical resistance technique had a limited success at sensing impact damage in AS4/3501-6 composites due to low initial resistances of the composites tested. doi:10.12783/issn. 2168-4286/2.2/Zhupanska

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.
