Discontinuous yielding transition of amorphous materials with low bulk modulus
(IOP Publishing, 2021-12)
The yielding transition of amorphous materials is studied with a two-dimensional Hamiltonian model that allows both shear and volume deformations. The model is investigated as a function of the relative value of the bulk ...
The effect of a product with three gluconeogenic precursors during the transition period on blood metabolites and milk yield in Chilean Holstein cattle
(Taylor and Francis Ltd., 2018)
The objective of this study was to determine the effect of a product containing calcium propionate 70 g/kg, propylene glycol 95 g/kg and glycerol 330 g/kg on blood β-hydroxy butyrate, non-esterified fatty acids and milk ...
Driving rate dependence of avalanche statistics and shapes at the yielding transition
(American Physical Society, 2016-02)
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 ...
Different universality classes at the yielding transition of amorphous systems
(American Physical Society, 2017-08)
We study the yielding transition of a two-dimensional amorphous system under shear by using a mesoscopic elasto-plastic model. The model combines a full (tensorial) description of the elastic interactions in the system and ...
Criticality in elastoplastic models of amorphous solids with stress-dependent yielding rates
(Royal Society of Chemistry, 2019-10)
We analyze the behavior of different elastoplastic models approaching the yielding transition. We propose two kinds of rules for the local yielding events: Yielding occurs above the local threshold either at a constant ...
Yielding of amorphous solids at finite temperatures
(American Physical Society, 2021-11)
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 elastoplastic model, with temperature introduced in the form of ...
RHEO-PIV OF A YIELD-STRESS FLUID IN A CAPILLARY WITH SLIP AT THE WALL.
(2013-02-19)
An analysis of the yielding and flow behavior of a model yield-stress fluid, 0.2 wt% Carbopol gel, in a capillary with slip at the wall has been carried out in the present work. For this, a study of the flow kinematics in ...
Properties of the density of shear transformations in driven amorphous solids
(IOP Publishing, 2021-03)
The strain load Δγ that triggers consecutive avalanches is a key observable in the slow deformation of amorphous solids. Its temporally averaged value (Δγ) displays a non-trivial system-size dependence that constitutes one ...
Estimation of singly transiting K2 planet periods with Gaia parallaxes.
When a planet is only observed to transit once, direct measurement of its period is impossible. It is possible, however, to constrain the periods of single transiters, and this is desirable as they are likely to represent ...
