Toward fractional gradient elasticity [PDF]

open access: yesJournal of the Mechanical Behavior of Materials, 2014
The use of an extension of gradient elasticity through the inclusion of spatial derivatives of fractional order to describe the power law type of non-locality is discussed. Two phenomenological possibilities are explored. The first is based on the Caputo

On gradient field theories: gradient magnetostatics and gradient elasticity [PDF]

open access: yesPhilosophical Magazine, 2014
In this work the fundamentals of gradient field theories are presented and reviewed. In particular, the theories of gradient magnetostatics and gradient elasticity are investigated and compared.

Non-Conventional Thermodynamics and Models of Gradient Elasticity [PDF]

open access: yesEntropy, 2018
We consider material bodies exhibiting a response function for free energy, which depends on both the strain and its gradient. Toupin–Mindlin’s gradient elasticity is characterized by Cauchy stress tensors, which are given by space-like Euler–Lagrange ...

Thermodynamically consistent gradient elasticity with an internal variable [PDF]

open access: yesTheoretical and Applied Mechanics, 2020
The role of thermodynamics in continuum mechanics and the derivation of proper constitutive relations is a topic discussed in Rational Mechanics. The classical literature did not use the accumulated knowledge of thermostatics and was very critical of the

Gradient elasticity solutions of 2D nano-beams

open access: yesApplications in Engineering Science, 2023
In this study, the exact analytical solutions of a two-dimensional linear homogeneous isotropic nano-beam in gradient elasticity are studied. Four different types of two-dimensional cantilever beams and related boundary conditions are considered.

A Proposition for a "Self-Consistent" Gradient Elasticity [PDF]

open access: yesJournal of the Mechanical Behavior of Materials, 2009
The notion of “self-consistent” boundary conditions in gradient elasticity is explored. They are introduced in the place of the “standard” boundary conditions commonly used in the formulation of gradient elasticity problems derived through corresponding variational principles.

The Green tensor of Mindlin’s anisotropic first strain gradient elasticity

open access: yesMaterials Theory, 2019
We derive the Green tensor of Mindlin’s anisotropic first strain gradient elasticity. The Green tensor is valid for arbitrary anisotropic materials, with up to 21 elastic constants and 171 gradient elastic constants in the general case of triclinic media.

Gradient-enriched linear-elastic tip stresses to perform the highcycle fatigue assessment of notched plain concrete [PDF]

open access: yesFracture and Structural Integrity, 2015
Gradient Elasticity (GE) allows the stress analysis to be performed by taking into account the size of the dominant source of microstructural heterogeneity via a suitable length scale parameter.

A new microcellular foaming strategy to develop structure-gradient thermoplastic polyurethane foams with enhanced elasticity

open access: yesMaterials & Design, 2023
Functionally graded polymer foams are advanced materials that exhibit great potential for applications in energy absorption, electromagnetic interference shielding, and high-elasticity due to the graded cellular structure for mechanical performance and ...
