Variation of microplastic limit during cyclic loading
Original language description
The microplastic limit (MPL) can be considered to be a stress (strain) at which plastic strains begin to occur in some micro-volumes of metal. The occurrence of these strains can not be determined by common methods but they can be detected by means of monitoring changes in magnetic permeability of a ferromagnetic material during application of mechanical load to a specimen [1]. Microplastic strains occur below the fatigue limit, namely as a result of dislocation movement in favourably oriented microregions in the metal lattice. With increasing load the dislocations are gradually piling-up at obstacles, firstly at grain boundaries, and due to that they form short-distance stress fields which obstruct magnetic domains to rotate to the direction of the acting load (strain).
