In the Eulerian description of metal forming operations usually rigid/incompressible viscoplastic material models are used. In this paper a quadrilateral 2-D finite-element formulation for incompressible viscoplastic flow analysis is developed. The element (QMITC) is based on mixed interpolation of

โฆ Synopsis
A new multiblock pressure-based ยฎnite element algorithm has been developed. This methodology implements a novel quadratic interpolation for the elemental pressure while using a bilinear interpolation for the velocity. Details of the algorithm and its multiblock foundation are provided along with a complete description of the implementation of the RNG-based kยฑe model. The results presented clearly demonstrate the validity and accuracy of this new approach for complex ยฏow problems such as diffusers.
