| Résumé : |
The influence of geometric section on the fatigue properties of EN8 steel was investigated by comparing the results obtained in fatigue tests on:
a/ Flat samples. b/ Welded samples. c/ Samples shaped to simulate the weld bead profile. It was found that the three sets of samples had significantly different fatigue characteristics. The fatigue loads which the samples could bear increased in the order welded, shaped and flat samples. Attempts were made to correlate these results by evaluating the stress concentration at the weld toe. Although this satisfactorily explained the differences in fatigue behaviour between the flat and the shaped samples it could not account for the results on the welded samples. Subsequent metallographic work using optical and electron optical techniques showed that microstructural changes in the heat affected zone were responsible for the lack of correlation. These observations contradict the results of previous published work. The conclusion drawn from this investigation can provide a basis for a rational desing code for fatigue loaded welded joints. |
