The phenomenon of fatigue crack closure has attracted continued interest over recent years. This paper concerns itself with one aspect of the phenomenon namely the effects of a single asperity on the crack face close to the crack tip and under dominantly plane strain Mode 1 loading conditions.

The plane strain, fatigue crack problem in which fracture surface asperities prevent closure is considered. A model in which closure contact can develop on a distribution of asperities is introduced. A comparison of closure behavior for one and for two asperities is made, and the effects of variatio

A numerical analysis of plasticity-induced fatigue crack closure based upon the finite difference method is presented. This new method permits modelling easily fatigue crack growth as well as contacts between fracture faces, without requiring sophisticated algorithms. The model is applied to a wide

The cyclic stress intensity threshold (AKTH) below which cracks will not propagate varies with length for short cracks. A model is proposed which relates AK rH to the crack ClOSUre StreSS arkbIg from fracture surface roughness. This is used to predict a variation in AK TH with crack length for surfa
