The Friction Models Integration in Calculation of Bulk Metal Forming Technologies by Finite Volume Method
نویسنده
چکیده
The usage of the finite volume method (FVM) for calculation of bulk metal forming working pressure is described in this paper. FVM is applied on two-dimensional orthogonal grids and colocated variable arrangement. The application of the FVM is done in case of solving the plastic flow during extrusion processes with different boundary conditions. The method of involving of the most frequently used friction models, Coulomb’s friction and constant friction law into the FVM algorithm is presented. Obtained numerical results are in agreement with the theoretical considerations.

In sheet metal forming processes with complex strain paths, a part is subjected to large plastic deformation. This severe plastic deformation leads to high plastic strain localization zones and subsequent accumulation of those strains. Then internal and superficial micro-defects and in other words ductile damage is created. This damage causes quality problems such as fracture. Therefore, design...
