Abstract
A wide range of sheet metal forming techniques has been developed to make it easier to produce intricate 3D objects. However, the knowledge still isn’t sufficient. The sheet metal extrusion method was examined in this research as one of the common sheet-bulk metal manufacturing technologies. Consideration of the flow-stress curve’s impact across a broad range of plastic strain and ductile damage played a pivotal role in constructing a realistic finite element method (FEM) model for the sheet metal extrusion process. The model was subsequently simulated using an Arbitrary Lagrangian-Eulerian (ALE) FEM, implemented in MSC. Marc. Validation of various phenomenological characteristics, such as metal flow behavior, shrinkage cavity, and the effects of different combinations of punch, extrusion outlet, and pre-punched hole diameter, was achieved by comparing the results with experimental data. These findings serve as a theoretical basis for the design of sheet metal extrusion processes.
