Deformation Study of Dual Equal Channel Lateral Extrusion Using FEM

摘要

The Plastic deformation characteristics of Dual Equal Channel Lateral Extrusion (DECLE or T-ECAP) has been studied by FEA using ANSYS version 7.1 software package. It is observed that the plastic deformation behaviour is more complex and the strain induced is highly localized. The extrusion force required is compared with the upper bound value published in literature. It is found from analysis that the strain is inhomogeneous and non uniform.
