Modelling and simulation of the grain deformation during extrusion of aluminium casting alloy (LM6) by finite element method

In any metal forming process, there's a high values of stresses and friction forces will generates due to sever interference between the contact surfaces. Extrusion process of aluminium casting alloy (LM6) is an obvious example for this case. Investigate the behavior of internal dislocation during the process is the main key to control the parameters which effects on the process efficiency. During this analysis; it's assumed that, the effects of...
