✦ Synopsis

Based on the model of Beevers and Carlson, the stresses on the fracture surface contacts in fatigue experiments are investigated. It will be shown that these stresses are often in the order of magnitude of the yield stress. Hence, for the consideration of contact shielding the size (area) of the contacts should be taken into account. Some experimental observations are presented, which illustrate that these stresses can produce a plastic deformation of fracture surface contacts which causes a partial loss of contact shielding.
