Finite Element Analysis of 3 Dimensional Steady State Deformation in Multi-stand Rod and Bar Rolling

유한 요소법을 이용한 다단 선재 압연의 3차원 정상 상태 변형 해석

Caliber design in bar and rod rolling depends on the designer's experience, which in general is acquired through costly trial-and-error process. As a prerequisite for developing a scientific approach to caliber design, we present a finite element model to simulate 3-D deformation of bars and rods occurring in multi-pass sequence. The results are compared with measurements obtained from POSCO for to assess the solution accuracy. The comparison shows that the simulation results agree well experiments.
