Investigation on the effect of geometric and structural notch on the fatigue notch factor in steel welded joints
Source abstract
Abstract
Abstract The paper presents an analysis of complex fatigue notch in welded joints, defined through the effect of both geometric notch and structural notch. The undertaken analysis involved fatigue tests conducted using S355N steel test pieces without a notch and with geometric, structural and complex notch. The test results were used to compare fatigue lives of notchless elements with fatigue lives of elements with each notch type. As an effect of numerous analysis fatigue notch factor was proposed, defined as a power function of number of load cycles and formulated for butt joints under different loadings. The results were compared with results obtained according to the Xiao-Yamada concept of theoretical notch factor.
