Abstract
This paper presents the development of an advanced finite element model for pre-dicting shear forces during the oblique-edge punching of Q235B steel, a material widely used in industrial applications. The model, developed in AN-SYS/LS-DYNA, investigates the influence of key parameters such as shear edge in-clination, strip thickness, punching depth, and lateral clearance. Results indicate that peak shear forces decrease significantly as the shear edge inclination increas-es from 4.0° to 4.8°. Furthermore, the optimal lateral clearance is found to be be-tween 0.2 mm and 0.4 mm, leading to improved tool performance and material integrity. Model validation shows an error range of 8.47 % to 10.87 %, confirming its accuracy and practical applicability. This study offers valuable insights for op-timizing tool design and enhancing punching efficiency in industrial settings, particularly in cold rolling mills. Future work will extend the model to a broader range of materials, incorporate advanced tool geometries, and account for thermal effects, thereby deepening the understanding of the shearing process and enabling further improvements in tool performance.
