FATIGUE CRACK INITIATION AND PROPAGATION IN METALS OF STRUCTURAL INTEREST

The mechansims of fatigue crack initiation and propagation in plastic metals is compared with the mechanisms in elasto-plastic metals. The microplastic behaviour of elasto-plastic metals is related to the stability of the strengthening mechanisms and to cyclic hardening or softening. Fatigue crack propagation models are compared with experimental observations and cumulative crack propagation is observed.
