Abstract
A semianalytical solution is presented for bending of moderately thick fully clamped laminated doubly curved panels using the extended Kantorovich method (EKM).The panel is subjected to uniform and nonuniform distributed loading and cut from a rectangular platform.Based on the first-order shear deformation theory, five highly coupled second-order partial differential equations in terms of displacement components are derived.Assuming separable functions for panel displacements together with the EKM converts the governing equations into double sets of ordinary differential equations with constant coefficients in terms of x and y.The resulting ODE systems are then solved iteratively until a level of prescribed convergence is achieved.Closed-form solutions can be presented for ODE systems in each iteration.Efficiency and rapid convergence of the solution technique are examined using several examples.Predictions of both deflection and stress resultants show very good agreement with other available results in the literature.It is also shown that the same formulation and solution method can be used to obtain results for spherical and cylindrical panels and rectangular plates.

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
