This study investigates the stress–strain behavior of a gun barrel under rapid firing conditions using the finite element method implemented in ANSYS Workbench. The numerical model considers the coupled effects of internal pressure and transient thermal loading to simulate the thermo-mechanical response of the barrel during continuous firing. The results, presented through stress–strain curves, contour plots, and time-dependent visualizations, reveal the evolution of stress concentration, plastic deformation, and material degradation in the barrel structure. The analysis demonstrates that repeated thermal and pressure cycles significantly affect the strength, fatigue resistance, and service life of the barrel. The findings provide a scientific foundation and computational reference for design optimization, material selection, manufacturing processes, and strength verification of modern artillery barrels, contributing to enhanced reliability and durability in high-rate firing applications.
