Abstract : Fatigue and crack growth data were obtained on five tee-fillet welded rib-stiffened plate type specimens 56 by 28 by 1-1/2 in. fabricated from HY-80 steel. The specimens were cyclically loaded in the NASL plate type fatigue machine which permits application of a uniform pressure to a plate that is simply supported at four edges. Data were obtained on the initiation and growth of fatigue cracks, fatigue life, effect of weld notch acuity, and effect of cyclical loading at lower nominal stresses after a fatigue crack of 20 percent of the depth of the specimen was formed.
