Investigating the Nature of Discontinuous Shear Thickening: Beyond a Mean-Field Description
Jetin E. Thomas, Abhay Goyal, Deshpreet Singh Bedi +3
Dense suspensions can undergo a dramatic increase in viscosity at a critical value of the shear stress. This phenomenon, termed discontinuous shear thickening (DST), has been attri…
Preserving elastic anisotropy with tessellations of granular packings
Annie Z. Xia, Dong Wang, Catherine La Riviere +3
Multiscale periodic metamaterials have been designed for numerous applications, such as impact absorption, acoustic cloaking, photonic band gaps, and mechanical logic gates. This p…
Energy-Conserving Contact Dynamics of Nonspherical Rigid-Body Particles
Haoyuan Shi, Christopher J. Mundy, Gregory K. Schenter +1
Understanding the contact dynamics of nonspherical particles beyond the microscale is crucial for accurately modeling colloidal and granular systems, where shape anisotropy dictate…
Shear jamming and nonlinear rheology of chocolate suspensions
Michel Orsi, Veeraj Shah, Mahesh Padmanabhan +2
We experimentally investigate the rheology of dark chocolate pastes in both industrially relevant pre-refined form and simplified model systems. Steady and oscillatory shear experi…
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…
Magnetic Interactions between Nanoscale Domains in Correlated Liquids
Mohammadhasan Dinpajooh, Giovanna Ricchiuti, Andrew J. Ritchhart +6
The formation of nanoscale domains (NDs) in correlated liquids and the emerging collective magnetic properties have been suggested as key mechanisms governing ion transport under e…
Predicting Magnetic Janus Particle Assembly with Differential Evolution Algorithm
Eric A. McPherson, Kenneth Kroenlein, Ilona Kretzschmar
Magnetic Janus particles allow access to complex, nonlinear assembled structures that may enable interesting new magnetorheological (MR) fluids with uniquely engineered field respo…
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…
Tuning the Size and Stiffness of Inflatable Particles
Nidhi Pashine, Dong Wang, Robert Baines +4
We describe size-varying cylindrical particles made from silicone elastomers that can serve as building blocks for robotic granular materials. The particle size variation, which is…
Dynamics of a Bottom-Heavy Janus Particle Near a Wall Under Shear Flow
Zohreh Jalilvand, Daniele Notarmuzi, Ubaldo M. Córdova-Figueroa +2
After our attention was brought to recent work by Pelargonio and Zaconne regarding the deviation of the white noise function for systems at very large shear, we have included the w…
The effect of stereochemical constraints on the structural properties of folded proteins
Jack A. Logan, Jacob Sumner, Alex T. Grigas +2
Proteins are composed of chains of amino acids that fold into complex three-dimensional structures. Several key features, such as the radius of gyration, fraction of core amino aci…
Protein folding as a jamming transition
Alex T. Grigas, Zhuoyi Liu, Jack A. Logan +2
Proteins fold to a specific functional conformation with a densely packed hydrophobic core that controls their stability. We develop a geometric, yet all-atom model for proteins th…
Rigid clusters in shear-thickening suspensions: a nonequilibrium critical transition
Aritra Santra, Michel Orsi, Bulbul Chakraborty +1
The onset and growth of rigid clusters in a two-dimensional (2D) suspension in shear flow are studied by numerical simulations. The suspension exhibits the lubricated-to-frictional…
The connection between polymer collapse and the onset of jamming
Alex T. Grigas, Aliza Fisher, Mark D. Shattuck +1
Previous studies have shown that the interiors of proteins are densely packed, reaching packing fractions that are as large as those found for static packings of individual amino-a…
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…
