Abstract
A finite-element method for static and free vibration analysis of axisymmetric circular nanoscale plates is presented based on the Gurtin-Murdoch continuum theory accounting for surface energy. Explicit solutions for stiffness and mass matrices and the load vector of a two-node plate finite element are derived by using a weighted residual formulation. The accuracy of the present finite-element model is verified by comparing with a set of analytical solutions for nanoplates. Simply supported plates show more influence of the surface energy effect compared with clamped plates. The first natural frequency is also affected, but higher natural frequencies as well as all mode shapes show minor influence of surface energy effects. The surface residual stress is found to be the key parameter that influences the deflections and natural frequencies. The current solutions clearly show the size-dependent response of nanoplates.

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 it
