dc.description.abstract | This study is dedicated to the effect of the heat treatment on the fatigue strength of an automobile rear axle beam and aims to propose a suitable and reliable methodology for the fatigue design. The rear axle beam is made of sheet metal (22MnB5); the microstructure is initially ferrito-pearlitic before the heat treatment and is martensitic after. A vast experimental campaign has been undertaken to investigate the behaviour, and more specially, the fatigue damage mechanisms observed for both treated and non-treated material, under different loading conditions: tension and shear test with different load ratios. In order to test the sheet metal in shear an original fatigue test apparatus is used. A probabilistic approach using the weakest link concept is introduced to model the fatigue behaviour. This approach leads naturally to a probabilistic Kitagawa type diagram, which in this case explains the relationship between the influence of the heat treatment and the microstructural heterogeneities. Integrate in a numerical model, this methodology permit to predict the effect of a local heat treatment on the fatigue strength of the components. |
