On fracture in finite strain gradient plasticity [PDF]
International Journal of Plasticity, 2016 In this work a general framework for damage and fracture assessment including the effect of strain gradients is provided. Both mechanism-based and phenomenological strain gradient plasticity (SGP) theories are implemented numerically using finite deformation theory and crack tip fields are investigated.

Strain gradient plasticity: energetic or dissipative? [PDF]
Acta Mechanica Sinica, 2015 It has been established by computation, and confirmed by analysis, for an infinite slab of strain-gradient sensitive material subjected to plane-strain tensile loading, that passivation of the lateral boundaries at some stage of loading inhibits plastic ...

Analysis of the size effect in the nanoscratching process of single crystalline and polycrystalline materials [PDF]
Scientific ReportsIn tribology, nanoscratch testing is used to evaluate the mechanical and tribological properties of materials by employing a nanoscale indenter. At this scale, size-dependent plasticity effects, particularly those related to scratch hardness, become ...

Plasticity of Bi2Te3-family thermoelectric crystals [PDF]
Nature CommunicationsThe exceptional plasticity discovered most recently in defective Bi2Te3 bulk crystal inspires the great interest on investigating the plasticity of other Bi2Te3-family bulk crystals. In this work, Bi2Se3, Sb2Te3, and their solid solutions with Bi2Te3 are

Contact of Rough Surfaces: An Incremental Model Accounting for Strain Gradient Plasticity
Lubricants, 2023 In the contact of rough surfaces, most contact patches are at the scale of micrometers, and thus, their contact deformation can be dominated by the size-dependent plasticity. In this paper, we propose a new strategy to analyze the role of strain gradient

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,
