순수 지르코늄의 등통로각압축(ECAP)공정에 대한 3차원 유한요소해석

초록

A lot of investigations have been made in recent years on the equal channel angular pressing(ECAP) which produces ultra-fine grains. The finite element method has been used to investigate this issue. In this paper, pure-Zirconium is considered for ECAP process by three dimensional finite element analysis. The effects of friction on the deformation behavior have been investigated and compared with two dimensional finite element analysis.
