P3K-4 Utilizing a Ray Technique to Calculate Multiple Reflections and Transmitted Waves from Layered Plates and Examine the Detection of Critical Disbonds, and Lamb Modes Generated
Bibliographic record
Abstract
This paper considers the problem of a single, or multilayer, isotropic plate and the problem of calculating the multiple reflections of acoustic waves within the plate, and the acoustic waves transmitted outside the plate (leaky waves). By using a ray method, and considering the paths traveled by the rays, it has been found that many of the multiple reflections will travel equivalent paths in space and time. Using superposition to combine the equivalent paths reduces the number of rays to track, and allows the process of calculations to be done in a time efficient manner. The use of the a ray model also gives initial results which are independent of properties of the incident acoustic waves. A separate set of calculations can be used expand the rays to a variety of more realistic acoustic waves, allowing a single result to be used for a variety of acoustic sources. The results from this model will be used to examine situations such as the detection of critical disbonds in plates, examination of the lamb modes which are generated, or examination of which situations produce the largest transmitted waves

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
