Structure-property relationships from universal signatures of plasticity in disordered solids
When deformed beyond their elastic limits, crystalline solids flow plastically via particle
rearrangements localized around structural defects. Disordered solids also flow, but without …

Tailoring the interfacial assembly of colloidal particles by engineering the mechanical properties of the interface
A Maestro - Current opinion in colloid & interface science, 2019 - Elsevier
Fluid interfaces can be used as a platform for promoting the direct and spontaneous self-
assembly of colloidal particles, where the driving force is the reduction in interfacial energy …

Directed aging, memory, and nature's greed
Disordered materials are often out of equilibrium and evolve very slowly in a rugged and
tortuous energy landscape. This slow evolution, referred to as aging, is deemed undesirable …

Relationships between structure, memory and flow in sheared disordered materials
KL Galloway, EG Teich, XG Ma, C Kammer… - Nature Physics, 2022 - nature.com
A fundamental challenge regarding disordered solids is predicting macroscopic yield—the
point at which elastic behaviour changes to plastic behaviour—from the microscopic …

Effect of directed aging on nonlinear elasticity and memory formation in a material
Disordered solids often change their elastic response as they slowly age. Using experiments
and simulations, we study how aging disordered planar networks under an applied stress …

State transition graph of the Preisach model and the role of return-point memory
The Preisach model has been useful as a null model for understanding memory formation in
periodically driven disordered systems. In amorphous solids, for example, the athermal …

Reversible-to-irreversible transition of colloidal polycrystals under cyclic athermal quasistatic deformation
Khushika, L Laurson, PK Jana - Physical Review E, 2023 - APS
Cyclic loading on granular packings and amorphous media exhibits a transition from
reversible elastic behavior to irreversible plasticity. The present study compares the …

Mechanical annealing and memories in a disordered solid
Shearing a disordered or amorphous solid for many cycles with a constant strain amplitude
can anneal it, relaxing a sample to a steady state that encodes a memory of that amplitude …
