Lattice models in micromechanics

M Ostoja-Starzewski - Appl. Mech. Rev., 2002 - asmedigitalcollection.asme.org
This review presents the potential that lattice (or spring network) models hold for
micromechanics applications. The models have their origin in the atomistic representations …

The postulations á la D'Alembert and á la Cauchy for higher gradient continuum theories are equivalent: a review of existing results

F dell'Isola, P Seppecher… - Proceedings of the …, 2015 - royalsocietypublishing.org
In order to found continuum mechanics, two different postulations have been used. The first,
introduced by Lagrange and Piola, starts by postulating how the work expended by internal …

Homogenization à la Piola produces second gradient continuum models for linear pantographic lattices

Y Rahali, I Giorgio, JF Ganghoffer… - International Journal of …, 2015 - Elsevier
In the present work, we show that the linearized homogenized model for a pantographic
lattice must necessarily be a second gradient continuum, as defined in Germain (1973) …

Linear elastic trusses leading to continua with exotic mechanical interactions

P Seppecher, JJ Alibert, FD Isola - Journal of Physics …, 2011 - iopscience.iop.org
We study the statics of some trusses, ie networks of nodes linked by linear springs. The
trusses are designed in such a way that a few number of floppy modes are present and …

How contact interactions may depend on the shape of Cauchy cuts in Nth gradient continua: approach “à la D'Alembert”

F Dell'Isola, P Seppecher, A Madeo - Zeitschrift für angewandte …, 2012 - Springer
Abstract Navier–Cauchy format for Continuum Mechanics is based on the concept of contact
interaction between sub-bodies of a given continuous body. In this paper, it is shown how …

Peridynamics as an upscaling of molecular dynamics

P Seleson, ML Parks, M Gunzburger… - Multiscale Modeling & …, 2009 - SIAM
Peridynamics is a formulation of continuum mechanics based on integral equations. It is a
nonlocal model, accounting for the effects of long-range forces. Correspondingly, classical …

[图书][B] Compendium on gradient materials

A Bertram - 2023 - Springer
Although already suggested in the middle of the 19th century, have material models that
include higher gradients of the kinematical variables become a blossoming field of research …

From molecular models¶ to continuum mechanics

X Blanc, C Le Bris, PL Lions - Archive for Rational Mechanics and …, 2002 - Springer
We present here a limiting process allowing us to write some continuum mechanics models
as a natural asymptotic of molecular models. The approach is based on the hypothesis that …

The influence of scale size on the stability of periodic solids and the role of associated higher order gradient continuum models

N Triantafyllidis, S Bardenhagen - Journal of the Mechanics and Physics of …, 1996 - Elsevier
Of interest here is the scale size effect on the stability of finitely strained, rate-independent
solids with periodic microstructures. Using a multiple scales asymptotic technique, we …

Linear plane wave propagation and normal transmission and reflection at discontinuity surfaces in second gradient 3D continua

F Dell'Isola, A Madeo, L Placidi - ZAMM‐Journal of Applied …, 2012 - Wiley Online Library
We study plane waves in second gradient solids and their reflection and transmission at
plane displacement discontinuity surfaces. The needed extension of the treatment adopted …
