Role of disorder in finite-amplitude shear of a 2D jammed material
NC Keim, PE Arratia - Soft matter, 2015 - pubs.rsc.org
A material's response to small but finite deformations can reveal the roots of its response to
much larger deformations. Here, we identify commonalities in the responses of 2D soft …

Multiperiodic orbits from interacting soft spots in cyclically sheared amorphous solids
NC Keim, JD Paulsen - Science Advances, 2021 - science.org
When an amorphous solid is deformed cyclically, it may reach a steady state in which the
paths of constituent particles trace out closed loops that repeat in each driving cycle. A …
