For the estimation of the service life of an automotive component like the exhaust system suffering high cycle fatigue in the case of multiaxial stress a simple calculation approach was developed by Tenneco. The generally used Dang Van fatigue model is modified so that it can be used for the prediction of the high cycle fatigue life with the help of stress solution from FEM simulation. The proposed approach is successfully applied at Tenneco.
