Geomimicry: Emergent Dynamics in Earth-Mediated Complex Materials
Shravan Pradeep, Emanuela Del Gado, Douglas J. Jerolmack +1
Soils and sediments are soft, amorphous materials with complex microstructures and mechanical properties, that are also building blocks for industrial materials such as concrete. T…
Athermal granular creep in a quenched sandpile
Nakul S. Deshpande, Paulo E. Arratia, Douglas J. Jerolmack
Creep is a generic descriptor of slow motions -- in the context of materials, it describes quasi-static deformation of a solid when subjected to stresses below the global yield, at…
Origins of complexity in the rheology of Soft Earth suspensions
Shravan Pradeep, Paulo E. Arratia, Douglas J. Jerolmack
When wet soil becomes fully saturated by intense rainfall, or is shaken by an earthquake, it may fluidize catastrophically. Sand-rich slurries are treated as granular suspensions,…
Soft matter physics of the ground beneath our feet
Anne Voigtländer, Morgane Houssais, Karol A. Bacik +24
Inspired by presentations by the authors during a workshop organized at the Princeton Center for Theoretical Science (PCTS) in January 2022, we present a perspective on some of the…
Understanding the rheology of kaolinite clay suspensions using Bayesian inference
Ranjiangshang Ran, Shravan Pradeep, Sébastien Kosgodagan Acharige +4
Mud is a suspension of fine-grained particles (sand, silt, and clay) in water. The interaction of clay minerals in mud gives rise to complex rheological behaviors, such as yield st…
Scaling of relaxation and excess entropy in plastically deformed amorphous solids
K. L. Galloway, Xiaoguang Ma, Nathan C. Keim +3
When stressed sufficiently, solid materials yield and deform plastically via reorganization of microscopic constituents. Indeed, it is possible to alter the micro-structure of mate…
Relationships among structure, memory, and flow in sheared disordered materials
K. L. Galloway, E. G. Teich, X-g Ma +7
A fundamental challenge for disordered solids is predicting macroscopic yield from the microscopic arrangements of constituent particles. Yield is accompanied by a sudden and large…
Quantification of plasticity via particle dynamics above and below yield in a 2D jammed suspension
K. L. Galloway, D. J. Jerolmack, P. E. Arratia
Failure of amorphous materials is characterized by the emergence of dissipation. The connection between particle dynamics, dissipation, and overall material rheology, however, has…
Plato's cube and the natural geometry of fragmentation
Gábor Domokos, Douglas J. Jerolmack, Ferenc Kun +1
Plato envisioned Earth's building blocks as cubes, a shape rarely found in nature. The solar system is littered, however, with distorted polyhedra -- shards of rock and ice produce…
Formation of stable aggregates by fluid-assembled solid bridges
Ali Seiphoori, Xiao-guang Ma, Paulo E. Arratia +1
When a colloidal suspension is dried, capillary pressure may overwhelm repulsive electrostatic forces, assembling aggregates that are out of thermal equilibrium. This poorly unders…
Viewing Earth's surface as a soft matter landscape
Douglas J. Jerolmack, Karen E. Daniels
The Earth's surface is composed of a staggering diversity of particulate-fluid mixtures: dry to wet, dilute to dense, colloidal to granular, and attractive to repulsive particles.…
Glassy dynamics of landscape evolution
Behrooz Ferdowsi, Carlos P. Ortiz, Douglas J. Jerolmack
Soil creeps imperceptibly downhill, but also fails catastrophically to create landslides. Despite the importance of these processes as hazards and in sculpting landscapes, there is…
Rheology of sediment transported by a laminar flow
M. Houssais, C. P. Ortiz, D. J. Durian +1
Understanding the dynamics of fluid-driven sediment transport remains challenging, as it is an intermediate region between a granular material and a fluid flow. Boyer \textit{et al…
