Modeling Gum Metal and other newly developed titanium alloys within a new class of constitutive relations for elastic bodies

open access: yesArchives of Mechanics, 2017
Many titanium alloys and even materials such as concrete exhibit a nonlinear relationship between strain and stress, when the strain is small enough that the square of the norm of the displacement gradient can be ignored in comparison to the norm of the ...

New applications of a generalized Hooke’s law for second gradient materials

open access: yesTheoretical and Applied Mechanics Letters, 2015
We provide analytical solutions to the problems of a circular bending of a beam in plane strain and the torsion of a non-circular cross-section beam, the beams obeying a second-gradient elasticity law proposed by the author, following a previous ...

Variational Formulations and Isogeometric Analysis of Timoshenko–Ehrenfest Microbeam Using a Reformulated Strain Gradient Elasticity Theory

open access: yesCrystals, 2022
This paper presents a novel non-classical Timoshenko–Ehrenfest beam model based on a reformulated strain gradient elasticity theory. The strain gradient effect, couple stress effect, and velocity gradient effect for vibration are included in the new ...

Modulated linear dynamics of nanobeams accounting for higher gradient effects [PDF]

open access: yes, 2016
We present some numerical results for the linear dynamics of nanobeams modulated by an axial force, basing on a recent proposal of literature that encompasses both the standard nonlocal elasticity, according to Eringen, and second-order strain ...

On weak solutions of the boundary value problem within linear dilatational strain gradient elasticity for polyhedral Lipschitz domains

open access: yesMathematics and mechanics of solids, 2021
We provide the proof of an existence and uniqueness theorem for weak solutions of the equilibrium problem in linear dilatational strain gradient elasticity for bodies occupying, in the reference configuration, Lipschitz domains with edges. The considered

Hyperelastic cloaking theory: Transformation elasticity with pre-stressed solids

open access: yes, 2012
Transformation elasticity, by analogy with transformation acoustics and optics, converts material domains without altering wave properties, thereby enabling cloaking and related effects.
