Application of a New Cohesive Zone Model in Low Cycle Fatigue.

Artikel, Bibliographie
Kurzbeschreibung (Abstract)
A cohesive zone model (CZM) for material fatigue analysis is presented. This cyclic CZM contains a damage variable and a corresponding damage evolution law. Considering the influence of the constraint condition for CZM, the triaxiality factor is also involved in this model. The new cyclic CZM can describe the different damage evolution mechanisms in the fatigue crack initiation and fatigue crack growth process. A unique set of model parameters is used. The material damage parameters included in the damage evolution law can be obtained from the material strain-life curve. Then they are used for fatigue crack growth calculation. The simulation results are compared with the experimental data in the very low cycle fatigue regime
