Abstract
Deformation history of the materials during equal channel angular pressing(ECAP) is calculated by FEM. The deformation behavior during ECAP is presented in terms of stretch ratio and shear angle with respect to those of simple shear deformation. Although many researchers have presented that the uniform and simple shear deformation during ECAP can be achieved, the material subjected through the ECAP die is shown to experience not a simple shear deformation but a complex deformation in this FEM analysis.
