Atomistic simulations of plasticity heterogeneity in gradient nano-grained FCC metals
Materials & Design, 2022 Gradient nano-grained (GNG) metals are an emerging class of heterogeneous structured materials with extraordinary mechanistic performances and unnatural plasticity mechanisms, which are unachievable in traditional homogeneous nanocrystalline metals. Here,

Interfaces within strain gradient plasticity: Theory and experiments [PDF]
Acta Materialia, 2006 In this paper, it is shown'that the occurrence of dislocation pileups across grain boundaries, as well as subsequent emission to the adjacent grains, is captured theoretically by gradient plasticity and confirmed experimentally by nanoindentation. From a theoretical point of view, this is accomplished (within a deformation theory framework applicable ...

A theory of strain-gradient plasticity with effect of internal microforce [PDF]
Theoretical and Applied Mechanics, 2017 This paper develops a theory of strain gradient plasticity for isotropic bodies undergoing small deformation in the absence of plastic spin. The proposed theory is based on a system of microstresses which include a microstress vector consistent with ...
