Odd dipole screening in disordered matter
Yael Cohen, Amit Schiller, Dong Wang +2
Disordered solids, straddling the solid-fluid boundary, lack a comprehensive continuum mechanical description. They exhibit a complex microstructure wherein multiple meta-stable st…
Tessellated granular metamaterials with tunable elastic moduli
Nidhi Pashine, Dong Wang, Jerry Zhang +5
Most granular packings possess shear moduli () that increase with the applied external pressure, and bulk moduli () that increase or remain constant with pressure. This paper…
Designing the pressure-dependent shear modulus using tessellated granular metamaterials
Jerry Zhang, Dong Wang, Weiwei Jin +5
Jammed packings of granular materials display complex mechanical response. For example, the ensemble-averaged shear modulus increases as a power-law…
Local and global measures of the shear moduli of jammed disk packings
S. Zhang, W. Jin, D. Wang +4
Strain-controlled isotropic compression gives rise to jammed packings of repulsive, frictionless disks with either positive or negative global shear moduli. We carry out computatio…
Microscopic Reversibility and Emergent Elasticity in Ultrastable Granular Systems
Yiqiu Zhao, Yuchen Zhao, Dong Wang +3
In a recent paper [Phys. Rev. X 12, 031021], we reported experimental observations of ``ultrastable'' states in a shear-jammed granular system subjected to small-amplitude cyclic s…
The structural, vibrational, and mechanical properties of jammed packings of deformable particles in three dimensions
Dong Wang, John D. Treado, Arman Boromand +4
We investigate the structural, vibrational, and mechanical properties of jammed packings of deformable particles with shape degrees of freedom in three dimensions (3D). Each 3D def…
Ultra-stable shear jammed granular material
Yiqiu Zhao, Yuchen Zhao, Dong Wang +3
Dry granular materials such as sand, gravel, pills, or agricultural grains, can become rigid when compressed or sheared. At low density, one can distort the shape of a container of…
Spatially correlated rotational dynamics reveals strain dependence in amorphous particle packings
Dong Wang, Nima Nejadsadeghi, Yan Li +3
Microstructural dynamics in amorphous particle packings is commonly probed by quantifying particle displacements. While rigidity in particle packings emerges when displacement of p…
Bridging particle deformability and collective response in soft solids
John D. Treado, Dong Wang, Arman Boromand +3
Soft, amorphous solids such as tissues, foams, and emulsions are composed of deformable particles. However, the effect of single-particle deformability on the collective behavior o…
Sheared Amorphous Packings Display Two Separate Particle Transport Mechanisms
Dong Wang, Joshua A. Dijksman, Jonathan Bares +2
Shearing granular materials induces non-affine displacements. Such non-affine displacements have been studied extensively, and are known to correlate with plasticity and other mech…
Enlightening force chains: a review of photoelasticimetry in granular matter
Aghil Abed Zadeh, Jonathan Barés, Theodore A. Brzinski +10
A photoelastic material will reveal its internal stresses when observed through polarizing filters. This eye-catching property has enlightened our understanding of granular materia…
`Sinking' in a bed of grains activated by shearing
Hu Zheng, Dong Wang, Jonathan Barés +1
We show how a weak force, , enables intruder motion through dense granular materials subject to external mechanical excitations, in the present case stepwise shearing. A force a…
Local and global avalanches in a 2D sheared granular medium
Jonathan Barés, Dengming Wang, Dong Wang +3
We present the experimental and numerical studies of a 2D sheared amorphous material constituted of bidisperse photo-elastic disks. We analyze the statistics of avalanches during s…
Self-organized magnetic particles to tune the mechanical behaviour of a granular system
Meredith Cox, Dong Wang, Jonathan Barés +1
Above a certain density a granular material jams. This property can be controlled by either tuning a global property, such as the packing fraction or by applying shear strain, or a…
