For various engineering and industrial applications it is desirable to realize mechanical systems with broadly adjustable elasticity to respond flexibly to the external environment. Here we discover a topology-correlated transition between affine and non-affine regimes in elasticity in both two- and three-dimensional packing-derived networks. Based on this transition, we numerically design and experimentally realize multifunctional systems with adjustable elasticity. Within one system, we…

Mechanical metamaterials with negative compressibility transitions.
Network concepts are explored to design metamaterials exhibiting negative compressibility transitions, during which a material undergoes contraction when tensioned (or expansion when pressured), where an increase in deformation induces a discontinuous increase in response force.
Mechanical metamaterials at the theoretical limit of isotropic elastic stiffness
This work identifies a material geometry that achieves the Hashin–Shtrikman upper bounds on isotropic elastic stiffness, and finds that stiff but well distributed networks of plates are required to transfer loads efficiently between neighbouring members.
Auxetic metamaterials from disordered networks
It is established that pruned networks represent a promising platform for the creation of unique mechanical metamaterials by exploiting the networks’ susceptibility to tuning to design networks that possess a distribution of stiffer and more compliant bonds and whose auxetic behavior is even greater than that of homogeneous networks.
Designing allostery-inspired response in mechanical networks
It is shown that removal of a small number of bonds in a random elastic network can dramatically change its mechanical response, and long-range coupled mechanical responses are similarly easy to achieve in disordered networks.
Liquid-induced topological transformations of cellular microstructures.
A two-tiered dynamic strategy that achieves systematic reversible transformations of the fundamental topology of cellular microstructures, which can be applied to a wide range of materials and geometries and harness dynamic topologies to develop active surfaces with information encryption, selective particle trapping and bubble release.
Elasticity of floppy and stiff random networks.
Numerical simulations are used to compute the exponents which characterize the shear modulus, the heterogeneity of the response, and the network stiffening as a function of deltaz and derive these theoretically, thus allowing us to predict aspects of the mechanical response of glasses and fibrous networks.
Multi-step self-guided pathways for shape-changing metamaterials
General principles for designing mechanical pathways are established, opening up new avenues for self-folding media, pluripotent materials, and pliable devices in areas such as stretchable electronics and soft robotics.
Non-affine response : Jammed packings vs. spring networks
We compare the elastic response of spring networks whose contact geometry is derived from real packings of frictionless discs, to networks obtained by randomly cutting bonds in a highly connected
Static non-reciprocity in mechanical metamaterials
It is shown that it is possible to break reciprocity in static systems, realizing mechanical metamaterials that exhibit vastly different output displacements under excitation from different sides, as well as one-way displacement amplification.
Amorphous solids: their structure, lattice dynamics and elasticity
Abstract Amorphous solids fall into any reasonable definition of a solid. This means that it should be possible to describe amorphous solids in terms of an expansion in deviations from a well defined
