TL;DR: The onset of a typical plastic event is studied with precision, and it is shown that the mode of the system which is responsible for the loss of stability has structure in real space which is consistent with a quadrupolar source acting on an elastic matrix.

TL;DR: In this paper, a conceptual diagram of predominant interactions in flowing cementitious suspensions under simple shear, as a function of shear rate and solid fraction, is presented, with the objective to understand and classify the situations where, depending on composition and processing, one or other of the physical phenomena will control the macroscopic behavior.

TL;DR: In this paper, the authors performed an extensive numerical study of avalanche behavior in a two-dimensional Lennard-Jones glass at constant strain rates and showed that flip-flip correlations remain relevant at all realistic strain rates.

TL;DR: A normal mode analysis of the nonaffine elastic displacement field allows it to clarify its relation to the zero-frequency mode at the onset of failure and to the cracklike pattern which results from the subsequent relaxation of energy.

TL;DR: In this article, numerical simulations of an atomistic system undergoing plastic shear flow in the athermal, quasistatic limit are presented, where the system is shown to undergo cascades of local rearrangements associated with quadrupolar energy fluctuations, which induce system-spanning events organized into lines of slip oriented along the Bravais axes of the simulation cell.
