Components of Vane Yield Stress of Structured Food Dispersions
(Wiley Blackwell Publishing, Inc, 2005-10)
The vane technique was used to determine the static (s0s) and dynamic (s0d) yield stresses of six commercial foods: mayonnaise, mustard, ketchup, applesauce, and two brands of tomato puree (samples TD and TR). The samples, ...
Steady and dynamic shear rheological properties of acai pulp (Euterpe oleraceae Mart.)
(Elsevier Sci LtdOxfordInglaterra, 2009)
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 ...
Influence of temperature on the rheological behavior of jaboticaba pulp
(Soc Brasileira Ciencia Tecnologia AlimentosCampinasBrasil, 2007)
Early water stress on growth, development and yield of high retention cotton
(University of Queensland, 2010)
The Bollgard II cotton varieties, which contain two genes from Bacillus thuringiensis var kurstaki (Bt) that express proteins toxic to Helicoverpa spp. were recently released in Australia, and they have increased insect ...
Estudo dos limites de escoamento e de viscoelasticidade linear de material tixotrópico com tensão limite de escoamento
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2020-03-06)
Yield stress materials are characterized by presenting predominantly elastic behavior for low mechanical stress and predominantly viscous behavior for high mechanical stress. The yield stress is usually used to characterize ...
Atomistic simulation of single crystal copper nanowires under tensile stress: Influence of silver impurities in the emission of dislocations
(Elsevier, 2014)
The transition from elastic to plastic behaviour in single crystal copper nanowires under uniaxial tensile
stress at different concentrations of silver (0.0–0.5 at.% Ag) and at different temperatures (0.1, 100, and
300 ...
Modelagem e simulação da quebra do gel no reinício do escoamento de fluidos de perfuração
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2013-04-24)
The thixotropic fluid flow start-up is a significant problem in the oil well drilling operations. Depending on the start-up flow properties and the drilling fluid applied, significant pressure peaks may take place compromising ...
Relação entre o limite de viscoelasticidade linear e o limite de escoamento de um material elastoviscoplástico
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2016-08-24)
The yielding of elastoviscoplastic materials is usually associated to two critical quantities that must be surpassed for the material’s breakdown: the yield stress and the yield strain, which define the material’s yield ...
