Abstract
In this study the cold extrusion of Al alloys will be investigated by finite element analysis (FEA) using DEFORM 2D. Besides, theoretical calculations to find the required extrusion force will be done. Several FE-simulations have been performed for two different extrusion geometries and for different conditions of friction including high and low friction, to quantify the influence of friction on the extrusion force. The results from FEA and theory for cold extrusion are compared to see if there is good agreement. The correlation between the data obtained by theory and FEA is discussed.
