Mapping Thixo-Visco-Elasto-Plastic Behavior
Manuscript to appear in Rheologica Acta, Special Issue: Eugene C. Bingham paper centennial anniversary Version: February 7, 2017 Mapping Thixo-Visco-Elasto-Plastic Behavior Randy H. Ewoldt Department of Mechanical Science and Engineering, University of Illinois at Urbana-Champaign, Urbana, IL 61801, USA Gareth H. McKinley Department of Mechanical Engineering, Massachusetts Institute of Technology, Cambridge, MA, USA Abstract A century ago, and more than a decade before the term rheology was formally coined, Bingham introduced the concept of plastic flow above a critical stress to describe steady flow curves observed in English china clay dispersion. However, in many complex fluids and soft solids the manifestation of a yield stress is also accompanied by other complex rheological phenomena such as thixotropy and viscoelastic transient responses, both above and below the critical stress. In this perspective article we discuss efforts to map out the different limiting forms of the general rheological response of such materials by considering higher dimensional extensions of the familiar Pipkin map. Based on transient and nonlinear concepts, the maps first help organize the conditions of canonical flow protocols. These conditions can then be normalized with relevant material properties to form dimensionless groups that define a three-dimensional state space to represent the spectrum of Thixotropic Elastoviscoplastic (TEVP) material responses. *Corresponding authors: [email protected], [email protected] 1 Introduction One hundred years ago, Eugene Bingham published his first paper investigating “the laws of plastic flow”, and noted that “the demarcation of viscous flow from plastic flow has not been sharply made” (Bingham 1916). Many still struggle with unambiguously separating such concepts today, and indeed in many real materials the distinction is not black and white but more grey or gradual in its characteristics.

Modification of Bingham Plastic Rheological Model for Better Rheological Characterization of Synthetic Based Drilling Mud
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Covenant University Repository Journal of Engineering and Applied Sciences 13 (10): 3573-3581, 2018 ISSN: 1816-949X © Medwell Journals, 2018 Modification of Bingham Plastic Rheological Model for Better Rheological Characterization of Synthetic Based Drilling Mud Anawe Paul Apeye Lucky and Folayan Adewale Johnson Department is Petroleum Engineering, Covenant University, Ota, Nigeria Abstract: The Bingham plastic rheological model has generally been proved by rheologists and researchers not to accurately represent the behaviour of the drilling fluid at very low shear rates in the annulus and at very high shear rate at the bit. Hence, a dimensionless stress correction factor is required to correct these anomalies. Hence, this study is coined with a view to minimizing the errors associated with Bingham plastic model at both high and low shear rate conditions bearing in mind the multiplier effect of this error on frictional pressure loss calculations in the pipes and estimation of Equivalent Circulating Density (ECD) of the fluid under downhole conditions. In an attempt to correct this anomaly, the rheological properties of two synthetic based drilling muds were measured by using an automated Viscometer. A comparative rheological analysis was done by using the Bingham plastic model and the proposed modified Bingham plastic model. Similarly, a model performance analysis of these results with that of power law and Herschel Buckley Model was done by using statistical analysis to measure the deviation of stress values in each of the models. The results clearly showed that the proposed model accurately predicts mud rheology better than the Bingham plastic and the power law models at both high and low shear rates conditions.

Shear Thickening in Concentrated Suspensions: Phenomenology
Shear thickening in concentrated suspensions: phenomenology, mechanisms, and relations to jamming Eric Brown School of Natural Sciences, University of California, Merced, CA 95343 Heinrich M. Jaeger James Franck Institute, The University of Chicago, Chicago, IL 60637 (Dated: July 22, 2013) Shear thickening is a type of non-Newtonian behavior in which the stress required to shear a fluid increases faster than linearly with shear rate. Many concentrated suspensions of particles exhibit an especially dramatic version, known as Discontinuous Shear Thickening (DST), in which the stress suddenly jumps with increasing shear rate and produces solid-like behavior. The best known example of such counter-intuitive response to applied stresses occurs in mixtures of cornstarch in water. Over the last several years, this shear-induced solid-like behavior together with a variety of other unusual fluid phenomena has generated considerable interest in the physics of densely packed suspensions. In this review, we discuss the common physical properties of systems exhibiting shear thickening, and different mechanisms and models proposed to describe it. We then suggest how these mechanisms may be related and generalized, and propose a general phase diagram for shear thickening systems. We also discuss how recent work has related the physics of shear thickening to that of granular materials and jammed systems. Since DST is described by models that require only simple generic interactions between particles, we outline the broader context of other concentrated many-particle systems such as foams and emulsions, and explain why DST is restricted to the parameter regime of hard-particle suspensions. Finally, we discuss some of the outstanding problems and emerging opportunities.

A Review on Recent Developments in Magnetorheological Fluid Based Finishing Processes
© 2018 JETIR June 2018, Volume 5, Issue 6 www.jetir.org (ISSN-2349-5162) A REVIEW ON RECENT DEVELOPMENTS IN MAGNETORHEOLOGICAL FLUID BASED FINISHING PROCESSES Kanthale V. S., Dr. Pande D. W. College of Engineering Pune, India ABSTRACT-The recent engineering applications demand the use of tough, high intensity and high temperature resistant materials in technology, which evolved the need for newer and better finishing techniques. The conventional machining or finishing methods are not workable for the hard materials like carbides; ceramics, die steel. Magnetorheological fluid assisted finishing process is a new technique under development and becoming popular in this epoch. With the use of external magnetic field, the rheological properties of the MR fluid can be controlled for polishing the surfaces of components. An extended survey of the material removal mechanism and subsequent evolution of analytical MR models are necessary for raising the finishing operation of the MR fluid process. Understanding the influence of various process parameters on the process performance measures such as surface finish and material removal rate. The objective of this study is to do a comprehensive, critical and extensive review of various material removal models based on MR fluid in terms of experimental mechanism, finding the effects of process parameters, characterization and rheological properties of MR fluid. This paper deals with various advancements in MR fluid based process and its allied processes have been discussed in the making the developments in the future in these processes. KEYWORDS: Magnetorheological fluid (MR fluid), Process parameter, Surface roughness, Material removal rate 1. INTRODUCTION The modern engineering applications have necessitated high precision manufacturing.

The 17th International Conference on the Hydraulic Transport of Solids, The Southern African Institute of Mining and Metallurgy and the BHR Group, 2007. Rough-wall and turbulent transition analyses for Bingham plastics A.D. THOMAS* and K.C. WILSON† *Slurry Systems Pty Ltd, Australia †Queens University, Canada Some years ago, the authors developed an analysis of non- Newtonian pipe flow based on enhanced turbulent microscale and associated sub-layer thickening. This analysis, which can be used for various rheologic modelling equations, has in the past been applied to smooth-walled pipes. The present paper extends the analysis to rough walls, using the popular Bingham plastic equation as a representative rheological behaviour in order to prepare friction-factor plots for comparison with measured results. The conditions for laminar-turbulent transition for both smooth and rough walls are also considered, and comparisons are made with earlier correlations and with experimental data.

Lecture 1: Introduction
Lecture 1: Introduction E. J. Hinch Non-Newtonian fluids occur commonly in our world. These fluids, such as toothpaste, saliva, oils, mud and lava, exhibit a number of behaviors that are different from Newtonian fluids and have a number of additional material properties. In general, these differences arise because the fluid has a microstructure that influences the flow. In section 2, we will present a collection of some of the interesting phenomena arising from flow nonlinearities, the inhibition of stretching, elastic effects and normal stresses. In section 3 we will discuss a variety of devices for measuring material properties, a process known as rheometry. 1 Fluid Mechanical Preliminaries The equations of motion for an incompressible fluid of unit density are (for details and derivation see any text on fluid mechanics, e.g. [1]) @u + (u · r) u = r · S + F (1) @t r · u = 0 (2) where u is the velocity, S is the total stress tensor and F are the body forces. It is customary to divide the total stress into an isotropic part and a deviatoric part as in S = −pI + σ (3) where tr σ = 0. These equations are closed only if we can relate the deviatoric stress to the velocity field (the pressure field satisfies the incompressibility condition). It is common to look for local models where the stress depends only on the local gradients of the flow: σ = σ (E) where E is the rate of strain tensor 1 E = ru + ruT ; (4) 2 the symmetric part of the the velocity gradient tensor. The trace-free requirement on σ and the physical requirement of symmetry σ = σT means that there are only 5 independent components of the deviatoric stress: 3 shear stresses (the off-diagonal elements) and 2 normal stress differences (the diagonal elements constrained to sum to 0).

A Fluid Is Defined As a Substance That Deforms Continuously Under Application of a Shearing Stress, Regardless of How Small the Stress Is
FLUID MECHANICS & BIOTRIBOLOGY CHAPTER ONE FLUID STATICS & PROPERTIES Dr. ALI NASER Fluids Definition of fluid: A fluid is defined as a substance that deforms continuously under application of a shearing stress, regardless of how small the stress is. To study the behavior of materials that act as fluids, it is useful to define a number of important fluid properties, which include density, specific weight, specific gravity, and viscosity. Density is defined as the mass per unit volume of a substance and is denoted by the Greek character ρ (rho). The SI units for ρ are kg/m3. Specific weight is defined as the weight per unit volume of a substance. The SI units for specific weight are N/m3. Specific gravity S is the ratio of the weight of a liquid at a standard reference temperature to the o weight of water. For example, the specific gravity of mercury SHg = 13.6 at 20 C. Specific gravity is a unit-less parameter. Density and specific weight are measures of the “heaviness” of a fluid. Example: What is the specific gravity of human blood, if the density of blood is 1060 kg/m3? Solution: ⁄ ⁄ Viscosity, shearing stress and shearing strain Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion. Gases also have viscosity, although it is a little harder to notice it in ordinary circumstances.
