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 ...

Interface-Dominated Plasticity and Kink Bands in Metallic Nanolaminates
Crystals, 2023 The theoretical and computational framework of finite deformation mesoscale field dislocation mechanics (MFDM) is used to understand the salient aspects of kink-band formation in Cu-Nb nano-metallic laminates (NMLs).

Journal of the Mechanical Behavior of Materials, 2018 This article investigates the differences between the Aifantis and Gurtin-Anand strain gradient plasticity. The fact that Gurtin-Anand strain gradient plasticity is richer than the Aifantis strain gradient plasticity provides a basis for which we could ...

A critical assessment of theories of strain gradient plasticity [PDF]
Acta Materialia, 2009 Theories to extend plasticity to the micron scale have been in existence for over a decade, complemented by a growing body of experimental data. Here, materials and mechanics aspects of two prominent strain gradient theories of plasticity, due to Nix and Gao and to Fleck and Hutchinson, are assessed within the context of simple bending.

Questioning size effects as predicted by strain gradient plasticity
Journal of the Mechanical Behavior of Materials, 2013 The analytical solution of the elastic-plastic response of a two-phase laminate microstructure subjected to periodic simple shear loading conditions is derived considering strain gradient and micromorphic plasticity models successively. One phase remains

A Comparison of Plasticity Regularization Approaches for Geodynamic Modeling
Geochemistry, Geophysics, Geosystems, 2023 The emergence, geometry and activation of faults are intrinsically linked to frictional rheology. The latter is thus a central element in geodynamic simulations which aim at modeling the generation and evolution of fault zones and plate boundaries ...

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 ...

Strain gradient polycrystal plasticity for micro-forming [PDF]
AIP Conference Proceedings, 2016 The developments in the micro-device industry has produced a substantial demand for the miniaturized metallic components with ultra-thin sheet materials that have thickness dimensions on the order of 50-500 µm which are produced through micro-forming processes.
