# Yielding of amorphous solids at finite temperatures

@article{Ferrero2021YieldingOA, title={Yielding of amorphous solids at finite temperatures}, author={Ezequiel Ferrero and Alejandro B. Kolton and Eduardo A. Jagla}, journal={Physical Review Materials}, year={2021} }

We analyze the effect of temperature on the yielding transition of amorphous solids using different coarse-grained model approaches. On one hand we use an elasto-plastic model, with temperature introduced in the form of an Arrhenius activation law over energy barriers. On the other hand, we implement a Hamiltonian model with a relaxational dynamics, where temperature is introduced in the form of a Langevin stochastic force. In both cases, temperature transforms the sharp transition of the…

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 decay in time as γ̇…

We study the rheology of amorphous solids in the limit of negligible thermal fluctuations. General arguments indicate that the shear-rate dependence of the stress results from an interplay between…

A scaling description of the yielding transition in amorphous solids made of soft particles at zero temperature is proposed that relates the flow curve, the statistics of the avalanches of plasticity observed at threshold, and the density of local zones that are about to yield.
