Plasticity at the micron scale
WebbUltrasonic nanocrystal surface modification (UNSM) has a unique, mechanical, impact-based surface severe plastic deformation (S2PD) method. This newly mature technique finds diverse software in to aerospace, automotive, nuclear, biomedical, and chemical industries. The tough plastic deformation (SPD) during UNSM can generate gradient … WebbThis phenomenon is most commonly referred to as synaptic plasticity and can involve different cellular mechanisms over time. In the short term, typically in the order of minutes to 1 h, synaptic...

Webbaccompanying micron-scale plasticity, we aimed at identifying its origin as well. Two dif-ferent types of 2D DDD simulations were employed as well as a higher scale stochastic continuum plasticity model (SCPM). The latter considers the yield stress to be a local random variable which represents internal disorder originating from the inhomogeneities WebbCovers dislocation mechanism-based crystal plasticity theory and computation at the micron and submicron scale Presents crystal plasticity theory without size effect Deals with the 3D discrete-continuous (3D DCM) theoretic and computational model of crystal plasticity with 3D discrete dislocation dynamics (3D DDD) coupling finite element …

Hutchinson Abstract Over a scale which extends from about a fraction of a micron to tens of … WebbMicron-scale single-crystalline materials deform plastically via large intermittent strain bursts that make the deformation process non-deterministic. Here we investigate this stochastic phenomenon by analyzing the plastic response of an ensemble of specimens differing only in the initial arrangement of dislocations.
