Evolution of Adaptive Force Chains in Reconfigurable Granular Metamaterials
Sven Witthaus, Atoosa Parsa, Dong Wang +7
Under an externally applied load, granular packings form force chains that depend on the contact network and moduli of the grains. In this work, we investigate packings of variable…
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…
Mechanical response of packings of non-spherical particles: A case study of 2D packings of circulo-lines
J. Zhang, K. VanderWerf, C. Li +3
We investigate the mechanical response of jammed packings of circulo-lines, interacting via purely repulsive, linear spring forces, as a function of pressure during athermal, q…
Contact network changes in ordered and disordered disk packings
P. J. Tuckman, K. VanderWerf, Y. Yuan +4
We investigate the mechanical response of packings of purely repulsive, frictionless disks to quasistatic deformations. The deformations include simple shear strain at constant pac…
A Toeplitz property of ballot permutations and odd order permutations
David G. L. Wang, Jerry J. R. Zhang
We give a new semi-combinatorial proof for the equality of the number of ballot permutations of length and the number of odd order permutations of length , which is due to B…
