The energy landscape governs ductility in disordered materials

L Tang, H Liu, G Ma, T Du, N Mousseau, W Zhou… - Materials …, 2021 - pubs.rsc.org
Based on their structure, non-crystalline phases can fail in a brittle or ductile fashion.
However, the nature of the link between structure and propensity for ductility in disordered …

Models for the yielding behavior of amorphous solids

S Sastry - Physical Review Letters, 2021 - APS
Investigations of plastic deformation and yielding of amorphous solids reveal a strong

Interplay of rearrangements, strain, and local structure during avalanche propagation

G Zhang, SA Ridout, AJ Liu - Physical Review X, 2021 - APS
Jammed soft disks exhibit avalanches of particle rearrangements under quasistatic shear.
We introduce a framework for understanding the statistics of the progression of avalanches …

Microscopic precursors of failure in soft matter

L Cipelletti, K Martens, L Ramos - Soft matter, 2020 - pubs.rsc.org
The mechanical properties of soft matter are of great importance in countless applications, in

Scaling description of creep flow in amorphous solids

M Popović, TWJ de Geus, W Ji, A Rosso, M Wyart - Physical Review Letters, 2022 - APS
Amorphous solids such as coffee foam, toothpaste, or mayonnaise display a transient creep
flow when a stress Σ is suddenly imposed. The associated strain rate is commonly found to …

Finite-size study of the athermal quasistatic yielding transition in structural glasses

D Richard, C Rainone, E Lerner - The Journal of Chemical Physics, 2021 - pubs.aip.org
Upon external mechanical loading, amorphous solids, such as foams, colloids, or molecular

Metastability as a mechanism for yielding in amorphous solids under cyclic shear

M Mungan, S Sastry - Physical review letters, 2021 - APS
We consider the yielding behavior of amorphous solids under cyclic shear deformation and
show that it can be mapped into a random walk in a confining potential with an absorbing …

Finite-size effects in the nonphononic density of states in computer glasses
