TLDR
Stress time series caused by plastic avalanches in athermally sheared disordered materials are studied using particle-based simulations and a mesoscopic elastoplastic model and critical exponents different from mean-field predictions are found.Abstract:
We study stress time series caused by plastic avalanches in athermally sheared disordered materials. Using particle-based simulations and a mesoscopic elastoplastic model, we analyze system size and shear-rate dependence of the stress-drop duration and size distributions together with their average temporal shape. We find critical exponents different from mean-field predictions, and a clear asymmetry for individual avalanches. We probe scaling relations for the rate dependency of the dynamics and we report a crossover towards mean-field results for strong driving.read more

TL;DR: It is shown that the full set of hydromagnetic equations admit five more integrals, besides the energy integral, if dissipative processes are absent, which made it possible to formulate a variational principle for the force-free magnetic fields.

Random critical point separates brittle and ductile yielding transitions in amorphous materials
TL;DR: The results show that the variety of yielding behaviors found in amorphous materials does not necessarily result from the diversity of particle interactions or microscopic dynamics but is instead unified by carefully considering the role of the initial stability of the system.

Deformation and flow of amorphous solids: Insights from elastoplastic models
TL;DR: In this article, the authors review the physical insight provided by elastoplastic models into practical issues such as strain localization, creep and steady-state rheology, but also the fundamental questions that they address with respect to criticality at the yielding point and the statistics of avalanches of plastic events.

TL;DR: In this article, the authors simulate the production of bioethanol by using conversion factor from starch into bio-ethanol, and apply it to the scenario of growing sago palm along river bank (up to 200 m, 400m, 600m, 800m, and 1000m).
