Contact of Rough Surfaces: An Incremental Model Accounting for Strain Gradient Plasticity [PDF]
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

Journal of Materials Research and Technology, 2023 The particle/matrix interface of metal matrix composites (MMCs) can give rise to extra strength and then affect the local deformation behavior. This strengthening effect originates from the plastic strain gradients due to the incompatibility of plastic ...

A Brief Note on the Nix–Gao Strain Gradient Plasticity Theory [PDF]
Metals, 2018 The mathematical nature of the flow rule for the strain gradient plasticity theory proposed by Nix and Gao (W.D. Nix and H. Gao, J Mech Phys Solids 46(3), 411(1998)) is discussed based on the paradigm developed by Gurtin and Anand (M.E.

A potential for higher-order phenomenological strain gradient plasticity to predict reliable response under non-proportional loading. [PDF]
Proc Math Phys Eng Sci, 2019 We propose a plastic potential for higher-order (HO) phenomenological strain gradient plasticity (SGP), predicting reliable size-dependent response for general loading histories.

RECENT ADVANCES IN STRAIN GRADIENT PLASTICITY
Journal of the Society of Materials Science, Japan, 1998 In the paper three kinds of framework of strain gradient plasticity recently developed and their applications are reviewed: strain gradient plasticity for CS solid-the couple stress-theory, strain gradient plasticity for SG solid, and mechanism-based strain gradient (MSG) plasticity. The applications are mainly focussed on the fracture problems.
