- W2023127955 abstract "Some of the new technological trends in metal forming processes are focused on the development of net shape or near net shape forming processes, the resurgence of incremental technologies and the consideration of environmental factors that result in more sustainable processes. On this basis, indentation is an interesting field because of its characteristics: lower forces are required, complex dies are not necessary and they can be used as an alternative to some forging operations. In this study an indentation process has been simulated by the Finite Element Method assuming plane strain conditions. The geometrical parameters considered are the width, w, and the height, h, of the workpiece and they are related to the width of the punch, B. For the simulation of different lubrication conditions a Coulomb friction model between the workpiece and the punch has been assumed. The friction coefficient has been chosen in such a way that either frictionless and high friction conditions have been covered. Under these conditions a reduction of 5% has been applied by the punch to all the cases. The contact pressures, forces and plastic strains have been calculated. The results show that for small dimensions of the workpiece edge effects appear, whereas for large dimensions the higher the geometry of the workpiece and the friction, the higher the values of these variables." @default.
