Abstract：

The stress distribution and strength condition of multilayer flat container for extruding aluminium sheet with flange has been simulated by elastic FEM under different extrusion pressure, hole size and shrink fitting range. The results show that the distribution of shrink fitting pressure is not uniform on the shrink fitting interface, the allowed maximum extrusion pressure is 500MPa with present container of hole size 850mm×250mm and 600MPa with which the hole size being changed into 850mm×320mm.
