A Fracture Mechanics Study on the Fatigue Crack Propagation of the Pressure Vessel Pad Weldment
압력용기 패드부의 피로균열진전에 관한 파괴력학적 연구
Abstract
In studying the fatigue strength of fillet welded the section of pressure vessel pad, this study was to evaluate the effect of weld toe notch and to compare the results of numerical analysis with the results of fatigue experiments of fillet welded A5l6 grade 60 steel specimens. The fatigue life for the Bead welded specimen was about 1.4 times as much it as the 1Pad welded specimen. Also, The fatigue life for the 2Pad welded specimen was about 1.5 times as much it as the 1Pad welded specimen. In
