Plastic deformation evolution in aluminum alloy specimens under cyclic loading

The modern knowledge about processes of plastic deformation and failure of loaded solids is intimately associated with the concept of structural levels of deformation and failure. The problem of fatigue failure can also be studied within this concept. The present work pays main attention to the study of the fatigue failure processes occurring at structural levels of aluminium alloy from the level of a grain to the level of a specimen as a whole. This approach makes it possible to reveal some new features of material behavior under cyclic loading
