주철 보수 용접시 Hammer Peening에 의한 잔류응력 재분포에 관한 연구
A Study on the Redistribution of Residual Stress Induced by Hammer Peening after Cast Iron Welding
- 발행 : 2004.11.01
초록
The purpose of this study is to evaluate the effects of hammer peening on the redistribution of residual stress at the repair weldment of cast iron using FEA. The FEA results were verified by comparing with experimental results. The maximum residual stress at the repair weldment of cast iron sharply decreases by hammer peening. The effect of hammer peening on the residual stress increases with a decrease of working temperature of hammer peeing.
