Cyclic saturation
WebMechanisms of curvilinear and cyclic change: saturation and exhaustion Models of one-directional change assume that change in a certain direction induces further change in the same direction; models of curvilinear or cyclic change, on the other hand, assume that change in a certain direction creates the conditions for change in another (perhaps even … WebMar 28, 2015 · In cyclic saturation, a characteristic dislocation structure has developed in the bulk, and a pattern of slip traces or some sort of PSBs of highly localized slip is recognizable at the surface. Cyclic strain localization and subsequent fatigue crack initiation in PSBs, cf. §6 a , are probably the best-studied case of fatigue damage.
