Finite Element Analysis of Material Flow and Characterization of Tube Dimensions of Indirectly Extruded Tailored Aluminum Tubes

Abstract:

In this work the extrusion of tailored aluminum tubes is investigated. Therefore, a stepped mandrel was applied and moved in axial direction in order to vary the tube’s wall thickness. Since surface irregularities were observed on the tube’s surface in transition areas between the different wall thicknesses, the material flow was analyzed by FEM in order to clarify the origin of the surface defects. It was revealed that the inwardly directed material flow in combination with the lack of inward resistance when the mandrel step is moving in the region of the die bearing causes the geometric inhomogenities.
