Particle-scale origin of quadrupolar non-affine displacement fields in granular solids
Evan P. Willmarth, Weiwei Jin, Dong Wang +4
In this work, we identify the local structural defects that control the non-affine displacement fields in jammed disk packings subjected to athermal, quasistatic (AQS) simple shear…
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…
Universal mechanical response of metallic glasses during strain-rate-dependent uniaxial compression
Weiwei Jin, Amit Datye, Udo D. Schwarz +2
Experimental data on the compressive strength versus strain rate for metallic glasses undergoing uniaxial compression shows significant…
Homogeneous crystallization in cyclically sheared frictionless grains
Weiwei Jin, Corey S. O'Hern, Charles Radin +2
Many experiments over the past half century have shown that, for a range of protocols, granular materials compact under pressure and repeated small disturbances. A recent experimen…
Stress anisotropy in shear-jammed packings of frictionless disks
Sheng Chen, Weiwei Jin, Thibault Bertrand +2
We perform computational studies of repulsive, frictionless disks to investigate the development of stress anisotropy in mechanically stable (MS) packings. We focus on two protocol…
Hypostatic jammed packings of frictionless nonspherical particles
Kyle VanderWerf, Weiwei Jin, Mark D. Shattuck +1
We perform computational studies of static packings of a variety of nonspherical particles including circulo-lines, circulo-polygons, ellipses, asymmetric dimers, and dumbbells to…
