A Study on the Influence Residual Stresses on Fatigue Crack Growth Behaviors in the Butt Welded Plate
Butt 용접판재에서의 피로균열성장거동에 미치는 잔류응력의 영향에 관한 연구
Abstract
In this study, the purpose is to investigate the influence of initial residual stresses on the fatigue crack growth behaviors after the distribution of initial residual stresses Is measured when the crack is growing from the compressive residual stresses field to the tensile residual stress field. Also, the Influence of the variation of residual stress distribution on the fatigue crack growth behaviors at the crack tip is studied when the initial crack li applied on base metal, weld metal and HAZ respectively.
