Abstract

fetched live from OpenAlex

The finite layer method is the most efficient numerical method for three-dimensional analysis of simply supported rectangular plates. Using this method, the three-dimensional analysis is transformed into one-dimensional analysis by virtue of the orthogonal properties of trigonometric interpolation functions. In the present study, the finite layer method is extended to the thermal buckling analysis of symmetrical cross-ply piezoelectric composite plates with full coupling between the thermal, electrical and mechanical fields. The pre-buckling state of the plate is assumed to be steady. Thus, the initial temperature distribution in the plate is independently determined based on the equation of heat conduction, and the associated thermal stresses are computed accordingly. The geometrical stiffness matrix is then formed in the same manner as in the elastic three-dimensional buckling analysis, and the critical temperature rise and buckling modes are obtained by solving the related matrix equations. Numerical examples are presented to verify the proposed method. The critical temperature rise is determined for both the adiabatic and isothermal buckling processes. The thermal buckling behaviours of some piezoelectric laminates and the effects of the thermo-electro-mechanical coupling are also investigated.

Not 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.
