Suitable combination of a mean-stress correction method and a stress type for the fatigue analysis of aluminium alloy wheels under radial loading

Finite element analysis (FEA) of the wheel radial fatigue test involves the selection of a combination of a mean-stress correction method and a stress type. This study aims to find the combination(s) of a mean-stress correction method and a stress type suitable for this application. In this work, the Gerber and Goodman mean-stress correction methods are compared when they are used in combination with the absolute maximum principal, signed von Mises and von Mises stresses. The effectiveness of each combination of a mean-stress correction method and a stress type in predicting fatigue failure in the wheel radial fatigue test was evaluated by comparing simulation results obtained by each combination method with experimental results. The results in this work suggest that using the Gerber or Goodman mean-stress correction method with the absolute maximum principal stress is suitable for the fatigue analysis of aluminium alloy wheels under radial loading.
