Particle-based simulations of discontinuous shear thickening (DST) and shear jamming (SJ)
suspensions are used to study the role of stress-activated constraints, with an emphasis on …

Hypothesis: A number of dense particle suspensions experience a dramatic increase in
viscosity with the shear stress, up to a solid-like response. This shear-thickening process is …

Dense suspensions are a prototype of fluid that can dynamically enhance their viscosity to
resist strong forcing. Recent work established that the key to a large viscosity increase …

Dispersing small particles in a liquid can produce surprising behaviors when the solids
fraction becomes large: rapid shearing drives these systems out of equilibrium and can lead …

Soft composite solids are made of inclusions dispersed within soft matrices. They are
ubiquitous in nature and form the basis of many biological tissues. In the field of materials …

Dry granular materials, such as sand, gravel, pills, or agricultural grains, can become rigid
when compressed or sheared. Under isotropic compression, the material reaches a certain …

Cement is an essential construction material due to its ability to flow before later setting,
however the rheological properties must be tightly controlled. Despite this, much …

In a recent paper (Zhao et al., Phys Rev X, 2022, 12: 031,021), we reported experimental
observations of “ultrastable” states in a shear-jammed granular system subjected to small …

Discontinuous shear thickening and dynamic shear jamming can be observed in the dense
granular suspension. Here, we determine the criterion for the occurrence of shear jamming …

We experimentally and theoretically study impacts into dense cornstarch and water
suspensions. We vary impact speed as well as intruder size, shape and mass, and we …
