Despite the large number of works devoted to the analysis and quantitative determination of the influence of crack closure on the indices of cyclic crack resistance of materials, there has not been reliable information on the conditions of occurrence of one mechanism of crack closure or another, and the degree of its influence on the kinetics of fatigue cracks. The results of investigations of fractures in the zones of contact of fatigue crack edges have been limited and unsystematic. In this connection, the purpose of this work is to further develop concepts of the nature of the crack closure phenomenon and its influence on fatigue crack growth.
