Notes:
Models describing the critical steps in the manufacturing process of aluminum alloywheels were integrated with a model of in-service loading to predict component fatigueperformance. A multiscale solidification model was coupled with models of the subsequent heattreatment and machining to predict the residual stress distribution in a finished wheel. A secondmultiscale model was incorporated into a service model to relate the pore size and local stress stateto fatigue performance. The predictions resulting from this through process modeling approachhave been validated by comparisons with a series of measurements: 1) thermocouple measurementsduring casting; 2) characterization of pore size and distribution using X-ray microtomography andoptical metallography; 3) residual strain measurements on finished wheels; 4) in-service strainmeasurements during a rotating bend test; and 5) in-service fatigue performance during rotatingbend tests
