Abstract
This paper presents a mathematical model developed for the dynamic analysis of ring-stiffened conical shell subject to a flowing fluid.The proposed approach combines classical shell theory and the finite element method, making use of displacement functions derived from exact solutions of Sanders' shell equations.Mass and stiffness matrices are determined by precise analytical integration of the equations of motion.The analysis of the shell-fluid interface involves leveraging the velocity potential, Bernoulli's equation, and impermeability conditions to determine an explicit expression for fluid dynamic pressure.Three distinct force vectors induced by the fluid (called the inertial, centrifugal, and Coriolis forces) can be determined through analytical integration of fluid dynamic pressure over structural shape functions.The influence of physical and geometrical parameters on the fluid-structure system has been considered in the numerical solutions.This study explores the influence of geometric parameters, stiffener quantity, cone angle, and applied boundary conditions on the natural frequency and instability characteristics of fluid-loaded ring-stiffened conical shells.When these results are compared with corresponding ones available in the open literature, both theoretical and experimental, very good agreement is obtained.

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
