Nonlocal theory of curved rods. 2-D, high order, Timoshenko’s and Euler-Bernoulli models

open access: yesCurved and Layered Structures, 2017
New models for plane curved rods based on linear nonlocal theory of elasticity have been developed. The 2-D theory is developed from general 2-D equations of linear nonlocal elasticity using a special curvilinear system of coordinates related to the ...

Fractional continua for linear elasticity

open access: yesArchives of Mechanics, 2014
Fractional continua is a generalisation of the classical continuum body. This new concept shows the application of fractional calculus in continuum mechanics. The advantage is that the obtained description is non-local.

A mixed operator approach to peridynamics

open access: yesMathematics in Engineering, 2023
In the present paper we propose a model describing the nonlocal behavior of an elastic body using a peridynamical approach. Indeed, peridynamics is a suitable framework for problems where discontinuities appear naturally, such as fractures, dislocations,

A note on the uniqueness of 2D elastostatic problems formulated by different types of potential functions

open access: yesOpen Physics, 2018
New additional conditions required for the uniqueness of the 2D elastostatic problems formulated in terms of potential functions for the derived Papkovich-Neuber representations, are studied.

Micropolar curved rods. 2-D, high order, Timoshenko’s and Euler-Bernoulli models

open access: yesCurved and Layered Structures, 2017
New models for micropolar plane curved rods have been developed. 2-D theory is developed from general 2-D equations of linear micropolar elasticity using a special curvilinear system of coordinates related to the middle line of the rod and special ...

Stress Response in Confined Arrays of Frictional and Frictionless Particles [PDF]

open access: yes, 2011
Stress transmission inside three dimensional granular packings is investigated using computer simulations. Localized force perturbation techniques are implemented for frictionless and frictional shallow, ordered, granular arrays confined by solid ...

An extension of assumed stress finite elements to a general hyperelastic framework

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2019
Assumed stress finite elements are known for their extraordinary good performance in the framework of linear elasticity. In this contribution we propose a mixed variational formulation of the Hellinger–Reissner type for hyperelasticity.

Gradient Schemes for Linear and Non-linear Elasticity Equations

open access: yes, 2014
The Gradient Scheme framework provides a unified analysis setting for many different families of numerical methods for diffusion equations. We show in this paper that the Gradient Scheme framework can be adapted to elasticity equations, and provides ...

Signorini problem as a variational limit of obstacle problems in nonlinear elasticity

open access: yesMathematics in Engineering
An energy functional for the obstacle problem in linear elasticity is obtained as a variational limit of nonlinear elastic energy functionals describing a material body subject to pure traction load under a unilateral constraint representing the rigid ...
