20.500.12556/RUL-177769 A hybrid radial basis function-finite difference method for modelling two-dimensional thermo-elasto-plasticity. Part 3, Application to thermo-mechanical modelling of continuous casting of steel billets This paper, Part 3 of a series, extends the previously developed strong-form hybrid radial basis function-finite difference (RBF-FD) method to model the thermomechanics of continuous casting (CC) of steel. Part 1 introduced the method for non-linear thermomechanics, and Part 2 applied it to the cooling of steel bars on a cooling bed. Here, a one-way coupled thermo-mechanical slice model is developed, where the temperature field provides thermal loading for the mechanical analysis. The previously introduced 2.5D formulation is adapted to include strand straightening. A visco-plastic material model, validated in our recent work, is used to describe material behaviour close to the mushy-zone temperatures. The analysis focuses on the solidified part of the strand, while the space discretisation remains constant and liquid-zone results are disregarded. Two hot-tearing criteria—temperature-based and stress-based are implemented and compared with experimental data, showing that the stress-based approach produces more realistic predictions. The influence of electromagnetic stirring, steel grade composition, and casting speed on hot-tearing susceptibility is explored. This study represents the first strong-form RBF-FD solution of CC thermomechanics, demonstrating that the hybrid RBF-FD can efficiently handle complex non-linear thermo-mechanical behaviour and allows for further process optimisation and defect mitigation in industrial CC. continuous casting of steel strong-form meshless numerical modelling radial basis function generated finite differences high temperature material modelling travelling slice model kontinuirano litje jeklo brezmrežno numerično modeliranje končne diference radialne bazne funkcije visokotemperaturno modeliranje materialov model potujoče rezine true false true Angleški jezik Slovenski jezik Članek v reviji 2026-01-07 08:17:56 2026-01-07 08:18:05 2026-07-04 04:21:50 0000-00-00 00:00:00 2026 0 0 23 str.
