J..., Norway Received 23 October 2009; accepted 9 August 2010 Abstract: The microstructure and crystallographic texture characteristics of an extruded ZK60 Mg alloy subjected to cyclic extrusion......
ratio. The existence of "training" and "memory" effects in red sandstone under cyclic point loading was proved. Key words: red sandstone; cyclic point loading; fatigue life; hysteresis loop... on the fatigue damage and irreversible deformation of salt rock subjected to uniaxial cyclic loading. Their results showed that the fatigue life of rock was mainly determined by its structure, amplitude and upper......

cyclic hardening both under multi-axial proportional and non-proportional loadings, while the cyclic additional hardening is shown under non-proportional loading, but the level is low. The multi-axial fatigue life decreases as the equivalent strain amplitude increases under both of multi-axial loadings. The fatigue life under non-proportional loading is less than that under proportional loading......
