In the CAD and CAX design and technologies of modern engineering structures -equipment, machines and their parts, professional engineers are frequently called upon to solve problems of a complex character, in which dynamic loads produced by a number of factors and agents play an increasingly part. The phenomenon of fatigue crack closure is known to strongly influence fatigue crack growth rates, hence directed modern structural materials development, accurate life prediction and the implementation of economic inspection procedures are dependant upon being able to quantify this phenomenon. The significant increasing of interest on fatigue crack closure determination in modern construction materials (especially in structural steels, Ti alloys, plastics and composites) and great interest in fatigue crack closure testing methods can be found. Much work has been done through experimental studies, (micro)mechanical modelling and numerical modelling to understand closure behaviour. However, the mechanisms of crack closure arising from microscopic roughness of the fatigue fracture surfaces, termed roughness-induced crack closure, are not fully understood. This paper presents historical review, methods and equipment for experimental observation, methods of computer modelling of fatigue crack tip closure concept.
