Classifying soft elastic lattices using higher-order homogenization
Basile Audoly, Claire Lestringant, Hussein Nassar
We propose a methodology for the homogenization of periodic elastic lattices that covers the case of unstable lattices, having affine (macroscopic) or periodic (microscopic) mechan…
Fixing non-positive energies in higher-order homogenization
Manon Thbaut, Basile Audoly, Claire Lestringant
Energy functionals produced by second-order homogenization of periodic elastic structures commonly feature negative gradient moduli. We show that this undesirable property is cause…
Asymptotic, second-order homogenization of linear elastic beam networks
Yang Ye, Basile Audoly, Claire Lestringant
We propose a general approach to the higher-order homogenization of discrete elastic networks made up of linear elastic beams or springs in dimension 2 or 3. The network may be nea…
Twisting instabilities in elastic ribbons with inhomogeneous pre-stress: a macroscopic analog of thermodynamic phase transition
Michael Gomez, Pedro M. Reis, Basile Audoly
We study elastic ribbons subject to large, tensile pre-stress confined to a central region within the cross-section. These ribbons can buckle spontaneously to form helical shapes,…
Effective continuum models for the buckling of non-periodic architected sheets that display quasi-mechanism behaviors
Connor McMahan, Andrew Akerson, Paolo Celli +2
In this work, we construct an effective continuum model for architected sheets that are composed of bulky tiles connected by slender elastic joints. Due to their mesostructure, the…
Simple deformation measures for Discrete elastic rods and ribbons
Kevin Korner, Basile Audoly, Kaushik Bhattacharya
The Discrete elastic rod method (Bergou et al., 2008) is a numerical method for simulating slender elastic bodies. It works by representing the center-line as a polygonal chain, at…
