【Abstract】 Based on the emphasis of 3D material forming in numerical simulation, this paper discusses the shortcomings of delaunay mesh. and put forward effective methods for meshing,re-meshing and criterion of hex-mesh . Finally, using the MSC.SuperForm software of FEM,aluminium section bar is simulated and analyzed in the process of continuous extrusion and cladding , which verifies the feasibility and reliability of hex-mesh.更多还原
