The large extrusion ratio forming of a complex thin-walled aluminum profile was simulated successfully in a new simulation system which was developed by integrated the Finite Element Method(FEM)and the multi-stage Finite Volume Method(FVM).

A new simulation system was developed by integrating finite element method(FEM) and finite volume method(FVM) based on the theories of large deformation elastic-plastic FEM and FVM,and the forming process of a complex hollow thin-walled aluminum profile 1633B of extrusion ratio λ=62.
