Numerical Investigations on Material Flow During Indirect Extrusion of Copper-Clad Aluminum Rods [PDF]
In the extrusion of clad composite materials with different flow stresses are usually used. This causes an inhomogeneous material flow which can induce sleeve or core fracture.

An Analysis Regarding the Variation of Necessary Force by the Indirect Extrusion Processes
AbstractIn comparison with other working procedures of hollow parts, indirect extrusion is characterized by high precision and productivity. Efficiency of the process imposed intense theoretical and experimental research over the years, resulting in widening the range of products manufactured [2,4–6,16].
