Computational Methods for Lifetime Prediction of Metallic Components under High-Temperature Fatigue

Computational Methods for Lifetime Prediction of Metallic Components under High-Temperature Fatigue

The issue of service life prediction of hot metallic components subjected to cyclic loadings is addressed. Two classes of lifetime models are considered, namely, the incremental lifetime rules and the parametric models governed by the fracture mechanics concept. Examples of application to an austeni...
