Prediction of Residual Stress in Straightening Process of SUS304 Wire

SUS304 와이어 직선화처리 공정 중 잔류응력 예측

It is known that fine straightness of micro-wire can be obtained by removing residual stress induced during the manufacturing processes. Generally, residual stress is removed or minimized through several drawing processes with heat treatment. In this study, the residual stress at each straightening process is calculated and monitored by finite element analyses and the main reason of stress change is investigated.
