FEM and FVM compound numerical simulation of aluminum extreusion processes
Trans. Noferrous Met. Soc. China, Apr. 2003, Vol, 13 No.2，-0001，（）：
The finite element method (FEM) and the finite volume method (FVM) nurmeircal sinrmalation methods have been widely used in forging industries to imrovethe quality of products and reduce the costs. Because of very concentrative largedeformation during the aluminum extrusion processes, it is very difficult to simulate the whole forming process only by using either FEM or FVM. In order to solve this problem, an FEM and FVM compoun simulation method was proposed. The theoretical equation of the compound sinmulation method were given and the key techniques were studied Then, the cofiguration of the compound simulation system was estabished. The tube extrusion process was simulated successfully so as to prove the validity of this approach for aluminum extusion processes.
