3. Results 3.1. Angle variation results

Figure 4 and Table 1 presents the results of service life as function of the loading angle. The example of  =  shows a lifetime reduction N DV  / N E = 73%

Fig. 4. Loading angle variation influence on service life according to Dang Van compared with Eurocodes and application example for  =24°, N DV  /N E =73%.
