On the Relations between the ‘Flow’ and ‘Solid’ Approaches in the Metal Forming Process

  • Wen-chao Zhang
Conference paper


In this paper we attempt to clarify the relation between the ‘Flow’ and ‘Solid’ approaches to the numerical analysis of the metal-forming process in order to set up a physically meaningful foundation for the ‘flow’ approach. Such clarification provides a better understanding of the viscoplastic flow formulation as applied to metal forming rather than relying on the analogy between Newtonian fluid flow and the behaviour of an incompressible elastic solid. In addition, some limitations of the ‘Flow’ approach are clearly exposed.
