Experimental and Analytical Durability Assessment of SAE 1045 Steel under Service Loadings

Abstract:

Durability assessment of automotive lower suspension arm has been studied under service loadings. The fatigue tests were conducting for the SAE 1045 steel based strain-controlled. To specify the material mechanical properties of the used material, a fatigue test under constant amplitude loading has been carried out then the results were provided for the finite element code. The finite element fatigue life were evaluated and compared with the experimental results. The accuracy and efficiency of the numerical models are demonstrated. This tool cannot be considered as a powerful alternative prior to the further experimental process. Instead, suitable fatigue prediction models under service loadings need to be developed.
