Abstract EN
Sheet metal extrusion is a metal forming process in which the movement of a punch penetrates a sheet metal surface and it flows through a die orifice; the extruded parts can be deflected to have an extrusion cavity and protrusion on the opposite side.
Therefore, this process results in a narrow region of highly localized plastic deformation due to the formation and microstructure effect on the work piece.
This research investigated the characteristics of the material-flow behavior during the formation and its effect on the microstructure of the extruded sheet metal using the finite element method (FEM).
The actual parts and FEM simulation model were developed using a blank material made from AISI-1045 steel with a thickness of 5 mm; the material’s behavior was determined subject to the punch penetration depths of 20%, 40%, 60%, and 80% of the sheet thickness.
The results indicated the formation and microstructure effects on the sheet metal extrusion parts and defects.
Namely, when increasing penetration, narrowing the die orifice the material flows through, the material was formed by extruding, and defects were visibility, and the microstructure of the material’s grains’ size was flat and very fine.
Extrusion defects were not found in the control material flow.
The region of highly localized plastic deformation affected the material gain and mechanical properties.
The FEM simulation results agreed with the experimental results.
Moreover, FEM could be investigated as a tool to decrease the cost and time in trial and error procedures.
