This paper reports some interesting observations on the response of laterally impacted steel tubes which in some respects have been considered to undergo an elastic shakedown. In an experimental study on the behaviour of axially compressed tubes under lateral impacts, it has been noticed that, after full development of plastic deformations in the impacted bodies, the structural system ceases to...

The cyclic plasticity behaviour and failure mechanism of the cathode material in lithium-ion batteries urgently need to be understood due diffusion-induced stress during charging-discharging process. Many researches have focused on shakedown ratcheting responses battery anode. However, systematic investigation is still lacking. In this paper, LiNixMnyCozO2 electrode subjected lithiation/delithi...

A high cycle fatigue (HCF) approach based on shakedown, crystal plasticity and cohesive zone theories is developed for metals. To take into account the effect of localized in grains grain boundaries, elastoplastic models are considered to calculate mechanical responses boundaries at mesoscopic scale, respectively. The Papadopoulos criterion used gauge property grain, a new criterion, shakedown ...

Turning IT -investments into organizational benefits is one of the key research objectives for information systems. There is a significant body of knowledge dealing with research on system development and management approaches. However, by leveraging crowd mechanisms, we believe that from a service systems perspective, after the rollout (also called shakedown phase) organizations still require ...
