Abstract:
The practical investigating and theoretic analysis Indicates that the rheologic action of the soft rock-soil could be accelerated by the dynamic loading, which induces more geotechnical engineering accidents and geologic disasters. The samples of marine deposit soft soil are collected in xiamen, and the dynamic stress-strain, the rheologic strain-time etc rheologic characteristics curves under the different breadth of dynamic loading of sinusoidal variation are tested using dynamic-triaxial device. The rheologic characteristics, rheologic rate and rheologic acceleration varietal process of four different breadths are analyzed. The research results indicate that all the samples are the same varietal process from decelerate rheology, relatively stable rheology to accelerate rheology stage. The dynamic strain slow growth and the rheologic process is relatively stable when the breadth of dynamic loading is low stress ranges of 10~20kPa.When the breadth of dynamic loading exceed 40kPa, the dynamic strain rapid growth and the rheologic is accelerate process till the samples destroy. The research results have academic and actual signification for us to open out the dynamic rheologic mechanics characteristic, explore the accelerating rheologic laws and the rheologic destabilizing dynamic condition of soft rock-soil under dynamic loading.

Abstract:
Abstract This paper is an attempt to highlight the problems faced by industrial rheologists. The problems are far more complex than subjects of usual academic pursuit. Because of the lack of scientific methods in both theory and instruments, the industrial rheologist often resort to empirical approach such as a use of the processing machines for processability evaluation. More fundamental approach is desirable. The examples are taken from high density polyethylenes and the period was 1960-1970. Although industry found solutions to the problems, the fundamental understandings have not been developed sufficiently.

Abstract:
Abstract Rheology is commonly used as a tool for analytics and quality control in latex technology. As soon as flow becomes essential for the structure measured in a scattering experiment we call it scattering from shear-ordered dispersions or rheologic scattering. In this paper it is shown that the structure of concentrated dispersions can with advantage be studied by scattering experiments. Theoretical and experimental aspects as well as examples of small-angle synchrotron x-ray and neutron scattering from colloidal dispersions, presented in the paper, are closely related to rheology.

Full text
Abstract:
The rheologic properties of a three-phase coal froth are critical to understanding the interfacial properties that are associated with its stability. Due to the fragile nature of froth, oscillatory rheology was used to make sure that the froths were not damaged during measurement. To reveal the relationship between a coal froth’s rheology and its stability, oscillatory rheology was used in this study. The viscoelastic behaviors of coal froths were analyzed, which illustrated that the storage modulus (G′) of a coal froth is larger than its loss modulus (G″), showing that coal froth is solid-like. The complex viscosity of the coal froths decreased with an increase in angular frequency, meaning that coal froth is shear-thinning. The dependence of froth rheology on ionic strength was investigated, which showed that an increase in ionic strength led to an enhancement of the storage modulus G′, as well as a decrease in tanδ (G″/G′). The coal froths tended to be more rigid and viscous with an increase in ionic strength. The mechanism of the effect of ionic strength on froth rheology was explored using electrical double layers, cryo-SEM, and particle fractions. As the ionic strength increased, the thickness of the electrical double layer decreased, which strengthened the interaction between the particles in the froth; in addition, the solid fraction in the froth increased with an increase in the ionic strength, so the value of G′ and the froth’s stability both increased.

Abstract:
I describe an experimental apparatus used to perform deformation experiments relevant to volcanology. The apparatus supports low-load, high-temperature deformation experiments under dry and wet conditions on natural and synthetic samples. The experiments recover the transient rheology of complex (melt ± porosity ± solids) volcanic materials during uniaxial deformation. The key component to this apparatus is a steel cell designed for high-temperature deformation experiments under controlled water pressure. Experiments are run under constant displacement rates or constant loads; the range of accessible experimental conditions include: 25 - 1100 °C, load stresses 0 to 150 MPa, strain rates 10⁻⁶ to 10⁻² s⁻¹, and fluid pressures 0-150 MPa. I present a suite of high-temperature, uniaxial deformation experiments performed on 25 by 50 mm unjacketed cores of porous Φ∼0.8) sintered rhyolitic ash. The experiments were performed at, both, atmospheric (dry) and elevated water pressure conditions (wet). Dry experiments were conducted mainly at 900 °C, but also included a suite of lower temperature experiments at 850, 800 and 750 °C. Wet experiments were performed at ∼650 °C under water pressures of 1, 2.5, 3, and 5 MPa, and at a fixed PH2O of ∼2.5 MPa for temperatures of ∼385, 450, and 550 °C. During deformation, strain is manifest by shortening of the cores, reduction of porosity, flattening of ash particles, and radial bulging of the cores. The continuous reduction of porosity leads to a dynamic transient strain-dependent rheology and requires strain to be partitioned between a volume (porosity loss) and a shear (radial bulging) component. The effect of increasing porosity is to expand the window for viscous deformation for dry melts by delaying the onset of brittle deformation by ∼50 °C (875 °C to 825 °C). The effect is more pronounced in hydrous melts (∼0.67 — 0.78 wt. % H₂0) where the viscous to brittle transition is depressed by ∼140 to 150 °C. Increasing water pressure also delays the onset of strain hardening due to compaction-driven porosity reduction. These rheological data are pertinent to volcanic processes where high-temperature porous magmas I liquids are encountered (e.g., magma flow in conduits, welding of pyroclastic materials).

Full text
Abstract:
Rheological behavior of two commercial brands of stirred yogurt were investigated using a Haake RV 20 rotational viscometer. For samples from both brands, the upward shear-rate flow behavior generally followed the Herschel-Bulkley model and the downward flow curves were linear. They demonstrated progressive structural degradation with repeated shearing. In the steady shear runs, all samples exhibited apparent thixotropic behavior and did not attain the equilibrium condition even after 60 min of continuous shearing. The time-dependent stress decay behavior of all samples were accurately described by Weltman's logarithmic time model. The rheological properties of both yogurt brands were qualitatively similar. Both Arrhenius and Turian models were found suitable to assess the temperature influence in the range 10-25$ sp circ$C.
The influence of pectin (0.0 to 0.5%) and fruit concentrates (raspberry and strawberry) (64$ sp circ$B, 0 to 10%) on the rheology of stirred yogurt were evaluated. The influence of storage time at 2$ sp circ$C up to a period of four weeks on the rheological properties of the two brands were evaluated.

Barra, Giuseppina. "The rheology of caramel." Thesis, University of Nottingham, 2004. http://eprints.nottingham.ac.uk/11837/.

Full text
Abstract:
The rheology of caramel was determined as a function of processing temperature and hydrocolloid additions. As the processing temperature increased the water content decreased and the caramel viscosity increased. X-ray diffraction showed that although crystalline fat was present, for the most part the sugars were in the amorphous state. The exception was the lowest water content caramel (7.9% water w.w.b.) which had been processed to a temperature of 122ºC. This had a small amount of crystalline fructose. Caramel rheology was assessed by rotational and capillary rheometry. Rotational rheometry gave information on the steady shear viscosity, the dynamic parameters (storage and loss moduli and related functions) and the creep compliance and recovery response. Capillary rheometry gave shear viscosities at high shear rates and an extensional viscosity. It was found that caramel without added hydrocolloids had behavior which was close to a Newtonian liquid. The only exception to this was the values obtained for the Trouton ratio which ranged from 10 to 40. This was considerably higher than the value of 3 for a Newtonian fluid and may reflect the difficulties in making measurements on these relatively low viscosity systems in the capillary rheometer. The viscosities obtained from steady shear, oscillation and creep were combined and three approaches were used to model the data as a function of measurement temperature and water content. An empirical statistical model using a second order polynomial, an Arrhenius fit and a Williams Landel Ferry (WLF) model. The former and the latter gave a good fit to the data although the constants used in the WLF model varied with the water content of the caramel. Arrhenius plots showed curvature particularly at low water contents. Incorporation of the hydrocolloids carrageenan and gellan gum into the caramel made the material non-Newtonian and elastic. For carrageenan incorporation in particular the Trouton ratio increased with carrageenan concentration reaching a value ~500 at a strain rate of 100s-1 for the caramel containing 0.2% carrageenan It was demonstrated that incorporation of carrageenan could be used to prevent cold flow in caramels processed at relatively high water contents. Glass transition temperatures were measured by differential scanning calorimetry and calculated from the temperature dependence of the shift factors used to superimpose the oscillatory rheological data. Generally there was agreement between the two approaches although for some gellan gum containing samples the rheological Tg was about 10ºC higher than the DSC value. Fragility calculated from the WLF constants for caramel was high as has been reported for sugars. The Tg for both caramel and sugar water mixtures calculated using the Couchman-Karastz equation in the water content of interest (9-15% w.w.b.) was some 30-40°C higher than measured. It is suggested that this disagreement could be related to the high fragility of the sugar water systems. Isoelectric point measurements using a streaming potential technique was shown to give information on the extent of the Maillard reaction and the presence of hydrocolloids.

Abstract:
The behaviour of paste is complex.  It has many unusual properties that do not fit with other engineering materials.  These can be linked to the volume effects that occur as the material is sheared. A multi-phase model based on a soil mechanic approach has been developed to consider the particle, liquid and gas components.  The volume is allowed to change during shearing and links these effects to the shear stress through pore fluid pressure and surface tension.  There is also a movable reference strain to allow the model the ability to simulate both cyclic and monotonic deformations in one system. Constrained pressure tests were conducted over a fixed strain amplitude cyclic deformation.  These were conducted in a series to consider the effects of strain rate, amplitude and pressure in a paste.  They were then analysed visually and statistically to find which of the variables were significant to the stress-strain response in paste. A further series of tests carried out with an increasing amplitude cyclic test.  This test was simpler but allowed a series of different pastes to be analysed without attempting to control the pore pressure in the materials.  A number of different responses were noted and a fuller picture of paste reaction was developed. Finally, the material model was matched to physical tests to evaluate the model’s ability to fit to different paste responses.  This was completed successfully with the use of an optimisation algorithm.

Abstract:
While the previous presentations have dealt with the experimental evidence linking flow patterns and shear stress to thrombosis and atherogenesis, this presentation will concentrate on the clinical evidence linking Theological abnormalities to macro and micro-circulatory ischaemia. Whole blood viscosity undoubtedly influences blood flow along larger vessels as suggested by Poiseuille. The two important determinants of whole blood viscosity are the red cell concentration and plasma fibrinogen.There is overwhelming epidemiological evidence that the red cell concentration is a primary risk factor for the development of essential hypertension, myocardial, cerebral and leg ischaemia. It is also a secondary risk factor in patients who already had a clinical episode of ischaemia in any of these territories. There is similar evidence in relation to a high plasma fibrinogen.Furthermore therapeutic haemodilution or defibrinogenation are increasingly used in the prevention and treatment of ischaemia.Haemorheological factors in the microcirculation are probably equally important but more difficult to assess clinically. The concept of a 'vicious viscous spiral' in ischaemic tissue is gaining increasing support. Whatever the initial cause of the ischaemia, important secondary haemorheological changes occur which can perpetuate or aggravate the ischaemia. Most of the changes known to occur locally in ischaemic tissues such as hypoxia, acidosis, release of serotonin and platelet activation have been shown to impair the deformability of blood cells. This will be particularly important if the perfusion pressure is also decreased and may result in capillary plugging and uneven distribution of flow in the microcirculation. Abnormal blood cell filtrability, just as whole blood viscosity, has been shown to be associated with acute as well as chronic ischaemia in most territories. Furthermore there is a correlation between the magnitude of the haemorheological changes measured and the subsequent clinical course of the patient following an ischaemic injury.The newest aspect of haemorheology to attract clinical attention is the role of the white cell in ischaemia. Epidemiological as well as recent experimental and clinical studies suggest that the Theologically activated white cell may be the most dangerous component of blood in terms of perpetuating and extending tissue ischaemia.The assessment of the Theological properties of blood should form an integral part of studies looking at the causes and possible therapy of all forms of acute and chronic ischaemia.

Abstract:
Overview The adhesion-aggregation of platelets to a site of vessel wall injury is a quintessential blood flow phenomenon. Firstly, platelets are driven to the vicinity of the vessel wall by a form of convective diffusion in which red cells both mechanically augment the effective platelet diffusivity (Turitto et al., Ind. Eng. Chem. Fund. 11:216-223, 1972; Grabowski et al., Ind. Eng. Chem. Fund. 11:224-232, 1972) and enhance the near-wall piatelet concentration (Ti11es and Eckstein, Microvasc Res., In press, 1987). Secondly, red cells subjected to physiologic shear forces are capable of secreting sufficient adenine nucleotides to induce primary platelet aggregation without themselves undergoing frank lysis (Reimers et al, Blood 64:1200-1206, 1984). This "humoral" effect of erythrocytes is likely to contribute to primary hemostasis in a shear stress-dependent manner. Thirdly, endothelial cells are able to modulate platelet aggregation at a site of vessel injury by producing prostacyclin (and perhaps other antithrombotic substances) in a manner which increases with vessel shear rate (Grabowski et al, Blood 62:301a, 1983); production for a large range of arterial shear rates appears to be limited by plasma-borne substrate (arachidonate). This manner of production ensures a concentration of prostacyclin in the near-wall region which remains relatively independent of shear rate.Imaging primary hemostasis. In our work, epi-fluorescence videomicroscopy has allowed real time imaging of platelet adhesion-aggregation to a simulated vessel wall injury. The injury model is an endothelial cell monolayer (ECM) across which, prior to ECM exposure to flowing blood, a 6-0 sterile suture is drawn in a direction transverse to flow. Microinjuries result which measure 70 ± 15μm (Mean ± SD) in width. The fluorescent label is the TAB murine monoclonal antibody (courtesy of Dr. R.P. McEver) directed against human platelet GPIIB, together with a fluorescein-conjugated goat F(ab')2 against murine inmunoglobulin. The injured ECM's, grown to confluence on rectangular cover glasses precoated with microfibrillar collagen, comprise one wall of a flow chamber mounted on a vertical microscope stage. On microinjury sites and at shear rates of 100 to 700 sec-1, computer-enhanced video images show adherence, remodelling and growth of chains of platelet aggregates. Aligned with the flow direction, these chains have a spacing of approximately 30)im, a length similar to the average endothelial cell diameter. One may speculate that such chains provide a scaffold for wound healing insofar as they are likely rich in agents chemotactic for leukocytes and in platelet-derived growth factor.Modulatory role of endothelium. When the ECM's are pre treated with 1.0 mM FC lysine acetyl sal icy late (LA), aggregate length increases (P<0.001) up totwo-fold, outflow levels by RIA of serum thromboxane B2 increase (8 of 8 paired runs), and outflow levels of prostacyclin by RIA for 6-Keto PGFiot decrease (5 of 7 paired runs). The Table gives data for one of four similar experiments at 270 sec-1 and following five minutes of flow. These data imply that products of ECM which are inhibitable by aspirin modulate local adhesion-aggregation; their inhibition, as by vasculitis or drugs, may give rise to thrombotic states.Bleeding disorders. Aggregate length is reduced in von Willebrand's disease (4 patients), Hermansky-Pudlak syndrome (2 patients), and after 300 mg oral aspirin (Tablet 4 donors). The reduction in the first two, however, is greater (P<0.01) than that for oral aspirin. With oral aspirin, further, there is a paradoxic increase in the percent platelet coverage of the injury area. Summary. Rheology has profound effects on the rate, structure, and modulation of primary hemostasis. Many of these effects can be studied via real-time, epi-fluorescence videomicroscopy of platelet adhesion-aggregation to a site of injury to an endothelial cell monolayer exposed to flowing blood. The model described has application to the study of thrombotic and hemostatic disorders and unstable angina.
