Abstract
The model has also been applied to a problem of WC-Co grade design for the improved performance. Validation experiments demonstrated the efficacy of model predictions. The simulation results agreed well with the observation found in the past literature that fatigue strength increases in a non-linear fashion with increase of Co amount.
