Self-consistent assessments for the effective properties of two-phase composites within strain gradient elasticity [PDF]

open access: yesMechanics of materials (Print), 2021
Analytical method for the second-order homogenization of two-phase composites within Mindlin-Toupin strain gradient elasticity theory is proposed. Direct approach and self-consistent approximation are used to reduce the homogenization problem to the ...

Irreducible decomposition of strain gradient tensor in isotropic strain gradient elasticity [PDF]

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2016
In isotropic strain gradient elasticity, we decompose the strain gradient tensor into its irreducible pieces under the n‐dimensional orthogonal group . Using the Young tableau method for traceless tensors, four irreducible pieces (), which are canonical, are obtained.

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 ...

On the strain gradient bending deformations

open access: yesJournal of the Mechanical Behavior of Materials, 2013
Bending deformations are reviewed in the context of strain gradient linear elasticity, considering the complete set of strain gradient components. It is well understood that conventional bending deformations depend on the collective uniaxial extension of

An asymptotic strain gradient Reissner-Mindlin plate model [PDF]

open access: yes, 2013
In this paper we derive a strain gradient plate model from the three-dimensional equations of strain gradient linearized elasticity. The deduction is based on the asymptotic analysis with respect of a small real parameter being the thickness of the ...

Nonlinear flexure mechanics of beams: stress gradient and nonlocal integral theory

open access: yesMaterials Research Express, 2021
In order to study the intrinsic size-effects, the stress gradient theory is implemented to a nano-scale beam model in nonlinear flexure. The nonlocal integral elasticity model is considered as a suitable counterpart to examine the softening behavior of ...

Decay for strain gradient porous elastic waves

open access: yesZeitschrift für angewandte Mathematik und Physik, 2023
AbstractWe study the one-dimensional problem for the linear strain gradient porous elasticity. Our aim is to analyze the behavior of the solutions with respect to the time variable when a dissipative structural mechanism is introduced in the system. We consider five different scenarios: hyperviscosity and viscosity for the displacement component and ...

Uniform materials and the multiplicative decomposition of the deformation gradient in finite elasto-plasticity [PDF]

open access: yes, 2008
In this work we analyze the relation between the multiplicative decomposition $\mathbf F=\mathbf F^{e}\mathbf F^{p}$ of the deformation gradient as a product of the elastic and plastic factors and the theory of uniform materials.

Nonlinear finite element analysis within strain gradient elasticity: Reissner-Mindlin plate theory versus three-dimensional theory

open access: yes, 2021
Nonlinear plate bending within Mindlin's strain gradient elasticity theory (SGT) is investigated by employing somewhat non-standard finite element methods.
