Definition of rheology in English:

rheology

noun

mass noun
  • The branch of physics that deals with the deformation and flow of matter, especially the non-Newtonian flow of liquids and the plastic flow of solids.

    • ‘Twenty-two papers are grouped into four contextual sections - the effect of fluids, microstructures and textures, deformation mechanisms and rheology and tectonics.’
    • ‘Overall, the deformation behavior and power-law rheology indicate an extremely broad range of timescales that underlie reversible changes in nuclear structure.’
    • ‘We explore the impact of rheology on actin-dependent cytoplasmic contraction, and find that although microtubules modulate contractile forces in vitro, their interactions are not purely mechanical.’
    • ‘We can do that because the topography that a planet can support is dependent upon structure and rheology.’
    • ‘They can inform us about the origin and ongoing development of many parts of the ocean basins, about former and current plate movements, about upper-Earth rheology, and about postglacial sea-level rise, among other processes.’
    • ‘In the case of taxol-stabilized extracts, we measure little difference in network rheology as compared to the untreated gels, yet observe striking differences in their contractile behavior.’
    • ‘The crowding could lead to polymerization or cross-linking events between macromolecules that might account for a change in rheology of the cytoplasm other than that caused by actin polymerization.’
    • ‘As with the cytoskeletal networks, rheology thus provides a valuable tool for studying networks composed of micrometer-scale clusters, where light scattering studies fail.’
    • ‘The stiffness of the constituent polymers of a mucous gel will also have a direct influence on the structure of the gel, particularly on characteristics such as rheology, film stability, and pore size.’
    • ‘None of these theological features were observed in our cell measurements, thereby suggesting that F-actin models are too simple to account for the complex rheology of the cells.’
    • ‘In this model, plant cell walls could be visualized as a ‘tangle’ of microfibrils, with wall rheology determined by spatial constraint upon further microfibril movement.’
    • ‘We did not rely on force curve analysis for quantitative evaluation of complex cellular rheology but instead used the indentation modulation procedure described below.’
    • ‘The power-law rheology seen here, as in a number of cellular systems, rules out any single timescale.’
    • ‘Thus, consistent with previous findings, these dense cells are likely to contribute to poor rheology of sickle cell blood at all O2 saturations.’
    • ‘Previous workers have attributed these differences to changes in rheology, i.e. brittle faulting in sandstones v. more ductile folding and faulting in dolostones.’
    • ‘Compactability is a measure of how easily the concrete is compacted and is the most-abused characteristic of vertical concrete's rheology.’
    • ‘We lack quantitative sedimentological and structural data on the Somma-Vesuvius debris avalanches, but we can make some interpretations regarding their rheology.’
    • ‘Knowledge of polymer rheology is essential in maintaining uniform textures in molded products such as, for example, an ice cream sandwich.’
    • ‘A molecular explanation for turgor-dependent changes in wall rheology is proposed in the quantitative molecular model of Passioura and Fry.’
    • ‘Post et al. showed that quartz rheology is sensitive to water fugacity, but the above extrapolations do not apply to identical values of water fugacity.’

Origin

1920s from Greek rheos ‘stream’ + -logy.
