Ramp-Duration-Controlled Symmetry-Protected Crossing and Mode Veering in Quasi-Static Thermal Buckling of a Perforated Variable-Angle-Tow Shallow Cylindrical Shell

This repository provides processed data, figure-generation scripts, frozen vector figures, representative fitted thermal-shell finite-element input decks, and documentation for a numerical study of ramp-duration-controlled symmetry-protected crossing and mode veering in quasi-static thermal buckling of a perforated variable-angle-tow shallow cylindrical shell. The package supports reproduction of the reported branch topology, thermal-prestress work decomposition, parameter-neighborhood studies, and cross-method IGA/finite-cell and fitted thermal-shell FEM comparisons. MATLAB scripts regenerate all 12 figures from the supplied processed data. Original large solver databases and commercial software executables are not redistributed; representative input decks and processed results are provided. This repository is journal-independent and can accompany the associated study through submission to different journals.
