## Abstract When large, progressive, deformation occurs under plastic or viscoβplastic conditions, elastic deformations are negligible and the material flows in a viscous manner. The flow is nonβNewtonian and the viscosity is a function of the current strain rates. An effective numerical treatment
The "nite element analysis of three-dimensional metal forming processes is generally subject to large computational burden due to its non-linearity. For economic computation, the mismatching re"nement, an e$cient domain decomposition method with di!erent mesh density for each subdomain, is developed
