... stress is directly related to the accuracy of fatigue assessment. In fatigue research of tubular joints, stress concentration factor (SCF) is defined as the ratio of hot spot stress to nominal stress. It was recommended (CIDECT, 2001; API, 2014; DNV, 2016; IIW, 2016) that nominal stress and SCF are used...

... of effective opening displacement for FEA EXPERIMENTAL RESULTS AND DISCUSSION Table 4 shows a summary of the CWP test results. The nominal stress and the global strain is calculated from the elongation between GL=450mm, and CMOD is obtained from the clip gauge displacement under maximum load. Figure 6 show...

... concentration factors in typical hot spots. The stress concentration factors are calculated based on a hot-spot stress and a nominal stress. The study documents stress concentration factors in critical hot spots for all analysed details, for 3 different load cases. By knowledge of the nominal stresses...

... ABSTRACT The present paper investigates the effects of joint flexibility on the nominal stresses in tubular lattice structures. It is shown that these effects are quite significant for both axial and bending nominal stresses. Two simple formulae (for axial and bending stresses) based on finite...
