The transient coupled thermo-piezoelectric response of a functionally graded piezoelectric hollow cylinder to dynamic loadings
Bibliographic record
Abstract
The transient, coupled thermo-piezoelectric response of a functionally graded, radially polarized hollow cylinder under dynamic axisymmetric loadings was investigated in the present paper. To take into account the simultaneous coupling of displacement, temperature and electric fields as well as non-Fourier heat conduction effect, the Chandrasekharaiah theory of generalized thermo-piezoelectricity was employed. Except thermal relaxation time which was taken to be constant, profiles of all other material properties follow a volume-fraction-based rule with different non-homogeneity indices for each property. To solve three governing coupled partial differential equations, the Galerkin finite-element method was used in the Laplace domain. To restore time, a numerical scheme was employed for the Laplace inversion. When the cylinder was exposed to a highly transient thermal loading, effects of the non-homogeneity index and thermal relaxation time on the results were 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.
