Three-dimensional Stability Analysis of Piezoelectric Antisymmetric Angle-Ply Laminates Using Finite Layer Method
Bibliographic record
Abstract
The finite layer method is the most efficient numerical method for 3D analysis of simply supported rectangular plates. In this method, the plate is divided into a number of finite layers. Within each finite layer, trigonometric functions are used for the in-plane interpolations of displacements, whereas polynomials are employed for the interpolations in the thickness direction. Thus, the 3D analysis is transformed into a series of 1D analyses, and the efficiency is enhanced significantly. In the present study, the finite layer method is extended to the stability analysis of piezoelectric antisymmetric angle-ply laminates, which may be also combined with some symmetrical cross-plies. Numerical results are presented to verify the proposed method. The effects of side-to-thickness ratio, aspect ratio, number of plies, fiber-orientation, and electrical conditions on stability behaviors of some piezoelectric laminates are investigated.

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.
