Protocol dependence of plasticity in ultrastable amorphous solids
While perfect crystals may exhibit a purely elastic response to shear all the way to yielding,
the response of amorphous solids is punctuated by plastic events. The prevalence of this …

Statistical dynamics of early creep stages in disordered materials
DF Castellanos, M Zaiser - The European Physical Journal B, 2019 - Springer
When materials are loaded below their short-term strength over extended periods, a slow
time-dependent process known as creep deformation takes place. During creep …

Controlled mechanical failure in glasses via designed spatial inhomogeneity
In glasses under mechanical load, intrinsic spatial inhomogeneities at specific locations in
the sample may cause shear banding. This allows us to initiate mechanical failure in a …

Emergence of a random field at the yielding transition of a mean-field elasto-plastic model
S Rossi, G Tarjus - Journal of Statistical Mechanics: Theory and …, 2022 - iopscience.iop.org
We study the mean-field limit of an elasto-plastic model introduced to describe the yielding
transition of athermally and quasi-statically sheared amorphous solids. We focus on the …
