摘要：
The univariant element, Q1P0, and the multivariant elements, Q1+P0 and R2+P0, are compared for the numerical simulation of the flow in extrusion dies. The pressure distribution obtained by using the Q1P0 element was found to be afflicted with the checkerboard pressure mode. On the other hand, the multivariant elements, Q1+P0 and R2+P0, gave accurate and physically reasonable velocity and pressure distributions. The computed values of the pressure drop across extrusion dies matched well with the pressure drop determined experimentally.
