An effect of a purely dissipative process of microstresses on plane strain gradient plasticity problems [PDF]

open access: yesTheoretical and Applied Mechanics, 2018
This article considers a plane strain gradient plasticity theory of the Gurtin–Anand model [M. Gurtin, L. Anand, A theory of strain gradient plasticity for isotropic, plastically irrotational materials Part I: Small deformations, J. Mech. Phys. Solids 53

Thermo-electro-mechanical behaviour of Nano-sized structures [PDF]

open access: yesMATEC Web of Conferences, 2020
Thermo-electro-mechanical behaviour of the nano-sized structures is analysed by the finite element method (FEM). The mechanical response of the nano-sized structures cannot be modelled with classical continuum theories due to the size effect phenomenon ...

A non-second-gradient model for nonlinear elastic bodies with fibre stiffness

open access: yesScientific Reports, 2023
In the past, to model fibre stiffness of finite-radius fibres, previous finite-strain (nonlinear) models were mainly based on the theory of non-linear strain-gradient (second-gradient) theory or Kirchhoff rod theory.

Theory and computation of higher gradient elasticity theories based on action principles [PDF]

open access: yes, 2017
In continuum mechanics, there exists a unique theory for elasticity, which includes the first gradient of displacement. The corresponding generalization of elasticity is referred to as strain gradient elasticity or higher gradient theories, where the ...

Buckling analysis of nonuniform nonlocal strain gradient beams using generalized differential quadrature method

open access: yesAlexandria Engineering Journal, 2018
Recently, it was shown that the length scales presented in nonlocal elasticity and strain gradient theory each describe a different physical and material properties of structures at small scales.

Pseudo Jahn-Teller Effect In The Origin Of Enhanced Flexoelectricity [PDF]

open access: yes, 2015
The controversy between the theory and experiment in explaining the origin of enhanced flexoelectricity is removed by taking into account the pseudo Jahn-Teller effect (PJTE) which, under certain conditions, creates local dipolar distortions of dynamic ...

Interfaces within strain gradient plasticity: Theory and experiments [PDF]

open access: yesActa 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 ...

Dislocation plasticity in thin metal films [PDF]

open access: yes, 2002
This article describes the current level of understanding of dislocation plasticity in thin films and small structures in which the film or structure dimension plays an important role. Experimental observations of the deformation behavior of thin films,
