    Abstract

    Experimental data on fatigue crack closure for two steels which present different mechanical properties are presented. The data are compared with experimental results obtained under similar test conditions on aluminum alloys. On the basis of such a comparison, an attempt is made to identify the most suitable engineering parameters to describe the fatigue crack closure behavior. As a result, it is shown how fatigue crack closure can be related to several basic features of fatigue crack growth.
