Rheological behaviour and spectroscopic investigations of cerium-modified AlO(OH)colloidal suspensions [PDF]
, 2011 The rheological behaviour of aqueous suspensions of boehmite (AlO(OH)) modified with different Ce-salts (Ce(NO3)3, CeCl3, Ce(CH3COO)3 and Ce2(SO4)3) was investigated at a fixed Ce/Al molar ratio (0.05).

Mechanical and deformation behaviors of sandy mudstone under triaxial unloading creep testing
Frontiers in Earth ScienceThe deformation caused by excavation unloading has a temporal effect, and its transient mechanical and rheological responses will change to some extent. Currently, most research findings on rheological behaviors are based on loading mechanics.

Creep and Fracture in Concrete: A Fractional Order Rate Approach [PDF]
, 2002 The paper analyses the interaction between strain-softening and time-dependent behaviour in the case of quasi-static fracture of concrete. A viscous element based on a fractional order rate law is coupled with a micromecanical model for the fracture ...

Three-dimensional rheological model for double-yield surface based on equivalent time
Yantu gongcheng xuebao, 2020 In order to describe shear contractibility, dilatancy and rheological properties of soils, Yin-Graham’s equivalent time method is used to derive a three-dimensional rheological model for double-yield surface.

Rheological models of biological cells
Bulletin of Taras Shevchenko National University of Kyiv. Series: Physics and Mathematics, 2022 The most important experimental methods of studying the mechanical properties of cells, as well as the most common rheological models, among which the discrete models of the micro/nanostructure of the cell and continuous models that allow calculating the modulus of elasticity and viscosity of the cell in normal and pathological conditions are discussed.

Simulated Short- and Long-Term Deformation in Coastal Karst Caves
Journal of Marine Science and Engineering, 2022 The self-balanced pressure arch theory is an important basis for excavation support in karst caves, but it is difficult to quantify the empirical theory in coastal areas.
