Title
Elasto - Plastic finite Element Analysis of Clad - Wire Drawing
김형섭Hyoung Seop kim, 이상현Sang Hyun Lee, 이동녕Dong Nyung Lee
Abstract
An analysis of clad-wire drawing has been made by the elasto-plastic finite element method. The results are in reasonable agreement with experimental ones. The effects of half die angle, friction and sheath metal are predicted. The softer sheath metal reduces internal cracking and the smaller half die angle makes the more homogeneous deformation in both the core and sheath layer. The maximum effective strain develops near surface because of smaller shear at the surface.
