An Accurate Upper Bound Solution for Plane Strain Extrusion through a Wedge-Shaped Die
An upper bound method for the process of plane strain extrusion through a wedge-shaped die is derived. A technique for constructing a kinematically admissible velocity field satisfying the exact asymptotic singular behavior of real velocity fields in the vicinity of maximum friction surfaces (the fr...
