Abstract:
In this paper we discuss properties of dense granular °ows and elaborate on some properties of a model which generalises the classical plastic potential model using elements of the double shearing model. It is shown how the model is embedded into a Cosserat continuum model. The proposed model recti¯es the ill-posedness of both the non-associated °ow rule and the double shearing model and may be used for both granular materials and also for metals which possess a micro-structure which is capable of rotation.

Abstract:
Preventing segregation in flowing granular mixtures is an ongoing challenge for industrial processes that involve the handling of bulk solids. A recent continuum-based modelling approach accurately predicts spatial concentration fields in a variety of flow geometries for mixtures varying in particle size. This approach captures the interplay between advection, diffusion and segregation using kinematic information obtained from experiments and/or discrete element method (DEM) simulations combined with an empirically determined relation for the segregation velocity. Here, we extend the model to include density-driven segregation, thereby validating the approach for the two important cases of practical interest. DEM simulations of density bidisperse flows of mono-sized particles in a quasi-two-dimensional-bounded heap were performed to determine the dependence of the density-driven segregation velocity on local shear rate and particle concentration. The model yields theoretical predictions of segregation patterns that quantitatively match the DEM simulations over a range of density ratios and flow rates. Matching experiments reproduce the segregation patterns and quantitative segregation profiles obtained in both the simulations and the model, thereby demonstrating that the modelling approach captures the essential physics of density-driven segregation in granular heap flow.

Abstract:
A granular material is usually an irregular packing of particles and its constitutive relationship is very complex. Previous researches have shown that the discrete element method is an effective tool for fundamental research of the behaviour of granular materials. In this research, discrete element modelling was used to obtain the macroscopic stress-strain behaviour of granular material in cavity expansion. The micro mechanical features and the mechanical behaviour of granular material at particle level have been investigated. A simple procedure was used to generate the samples with spherical particles and two-ball clumps. The influence of particle properties on the stress strain behaviour within an aggregate was investigated in biaxial test simulations. It was found that more angular clumps lead to sample more homogeneous and that the interlocking provided by the angular clumps induces a higher strength and dilation in the sample response. Interparticle friction was also found to have significant effect on the strength and dilation of the sample. The sample macromechanical properties can be obtained from these biaxial simulations. For investigating the effect of particle shape, the spherical or non-spherical(two-ball clump) particle shapes were used in the cavity expansion simulations. Monotonic loading was performed on a fan-shaped sample with various particle properties under a range of initial cavity pressures. The results were compared with calculated analytical solutions and existing experimental data in order to optimise the micro mechanical parameters governing the behaviour. The pressuremeter test data were adapted for this comparison since the theory of cavity expansion has been used to describe the pressuremeter tests in soil and rocks by many geotechnical researchers and engineers. This research showed that particle properties play an important role in soil behaviour of cavity expansion under monotonic loading. The contribution of this research is to present that it is possible to model a granular material of boundary value problem (cavity expansion) under static conditions, providing micro mechanical insight into the behaviour.

Abstract:
The permanent deformation of a pavement due to vehicle load is one of the important factors affecting the design life as well as the maintenance cost of a pavement. For the purpose of obtaining a cost-effective design, it is advisable to predict the traffic-loadinduced permanent pavement deformation. The permanent deformation in pavements (i.e. rutting) can be classified into three categories, including the wearing of the asphalt layers, compaction, and shear deformations. In the present study, discrete element analyses have been performed to predict the permanent deformation of a pavement when subjected to moving wheel loads. Note that the wearing of the asphalt layers has been disregarded. DEM biaxial test simulations have been carried out in terms of both unbonded and bonded granular materials. The typical stress-strain response, as well as the volumetric strain development, have been reproduced, in qualitative agreement with the experimental results. The factors affecting the mechanical behaviour of granular materials have been investigated, e.g. particle stiffness, sample compaction and parallel bond strength. In addition, the elastic properties, initial yield stress, strength parameters and so on have been analysed. These compression tests provided guidance for the selection of the particle parameters for the subsequent pavement simulation. The permanent deformation in unbonded pavements was represented under moving wheel loads, and proved to be qualitatively consistent with the laboratory tests. The initial self-weight stress had a significant effect on rutting. When the initial gravity stress was relatively high, both shakedown and surface ratchetting phenomena were observed for different loading levels. However, the accumulation of permanent deformation was continual for pavements with low gravity stress, even if the wheel pressure was small. Other factors affecting the rutting have been taken into consideration, e.g. specimen preparation, interparticle friction, etc. In the case of the single-layered pavement, permanent deformation ceased after the first wheel pass. Plastic deformation increased with the decrease in the self-weight stress. For the double layered pavement, the permanent deformation continually increased with wheel passes, probably owing to compaction of the bottom unbound layer. The pavement shakedown phenomenon was not observed prior to wheel pass 300. The permanent deformation increased augmentation of wheel pressure as well as decrease in the sample density and upper layer thickness. The residual stresses in both vertical and horizontal directions can be obtained using the measurement circle. For all the pavements in the current simulations, the vertical residual stress is nearly always zero, consistent with the equilibrium condition. In the case of the unbonded pavement, the large horizontal residual stress depends on the high initial gravity stress, instead of high wheel pressure or wheel pass number. For the single-layered pavement, the peak of the horizontal residual stress was observed near the pavement surface. The residual stress rises with the augmentation of the wheel pass number and the wheel pressure. In the double-layered pavement, the residual stresses are discontinuous at the interface between different pavement layers. The peak appears near the pavement surface and increases with the reduction in the upper layer thickness as well as the rise in wheel passes and wheel pressure. Nevertheless, residual stress is not apparent in the granular base. The probability density distribution was investigated in terms of the contact and bond forces. For the normal contact force, a peak generally appeared at small contact forces, followed by a drastic decrease and, after that, the probability density progressively approached zero. For the tangential contact force as well as the bond forces, in general, a peak of the probability distribution was observed at small contact forces, and then a sharp drop followed from the two flanks of the peak point. Finally, there was a gradual decrease until the probability density decayed to zero. The factors, e.g. pavement layer, wheel pass number and wheel pressure, mainly affect the probability distribution of the small contact or bond forces. For both single- and double-layered pavements, the absolute extrema of the bond forces in the top layer increased with the augmentation of the wheel pass number and the wheel pressure. For the unbonded pavement, the sliding contact ratio was studied and it was significantly affected by the pavement layer, initial gravity stress and sample compaction. The distribution of the pavement particle displacements were demonstrated. In the unbonded pavement, factors, such as wheel pressure and initial gravity, not only affect the distribution of the relatively large particle displacements but also increase the magnitude of the particle displacements. The directions of the large displacement vectors are diverse as the large gravity acceleration is assigned to the particles but are almost downward when the self-weight stress is small. In the single- or double layered pavement, factors, such as wheel pass number and wheel pressure, merely increase the values of the particle displacements. The distribution of the displacements is hardly affected. For the single-layered pavement, the large displacements were observed near the pavement surface and their directions are almost contrary to the movement direction of the wheel. In the double-layered pavement, relatively large particle displacements are widely distributed in the pavement. Their directions are in an almost vertical direction.

Abstract:
The main objective of this work is to model granular materials comprising particles of aspherical shape and investigate the effect of the grain shape on the hydraulic properties of the material. For this purpose, a Discrete Element Method code for clustered spheres was developed during the course of this work to simulate aspherical particles. The shape of the particles modelled mimics the morphology of real grains obtained from a shape library of real scanned particles for which development this thesis also contributed. The simulation tools are then used to construct models of real sands by simulating the settling under gravity and compaction of the grains. The hydraulic properties of the sand moels are then investigated via numerical simulations using two different approaches. First, we simulate low Reynolds numbers flow in granular packs using a Finite Element method within the Stokes flow approximation. Then we explore the applicability of the two-fluids approach to simulate fluid flow in the presence of solid obstacles and complex microstructures. By integrating the technologies developed during this work, it was possible to simulate the single phase flow in a wide range of Reynolds number in models of sand. The results obtained closely agree with available experimental data and empirical correlations for relatively clean and homogeneous sands. These results show that the hydraulic permeability can vary within a factor of two as a consequence of the particle shape. This indicates that for unconsolidated media the most important parameter with regards to fluid flow conductivity is the porosity.

Abstract:
Cone penetration testing (CPT) is one of the most versatile devices for in situ soil testing. With minimal disturbance to the ground, it provides information about soil classification and geotechnical parameters. Several researchers have used different numerical techniques such as strain path methods and finite element methods to study CPT problems. The Discrete Element Method (DEM) is a useful alternative tool for studying cone penetration problems because of its ability to provide micro mechanical insight into the behaviour of granular materials and cone penetration resistance. This study uses three-dimensional DEM to simulate the cone penetration testing of granular materials in a calibration chamber. Due to the geometric symmetry of this study a 90 degree segment of the calibration chamber and the cone penetrometer was initially considered followed by a 30 degree segment to allow for the simulation of smaller particle sizes and to reduce computational time. This research proposes a new particle refinement method, similar to the mesh refinement of finite-element modelling, in the sense that a large number of small particles were brought into contact with the cone tip, while the large particles were distanced further away from the cone, to reduce computational time effectively. Using a radius expansion method for sample preparation and assigning a constant mass to each particle in the sample was found to reduce computational time significantly with little influence on tip resistance. The effects of initial sample conditions and particle friction coefficient were found to have an important influence on the tip resistance. In addition, prohibiting particle rotation was found to increase tip resistance significantly compared to when the particles were permitted to rotate freely. Particle shape in this study was simulated by replacing the spheres with simple two-ball clumps and was found to have an important effect on the tip resistance. DEM simulations of biaxial tests were conducted to investigate the effect of initial sample conditions, particle shape and particle friction coefficient on the stress-strain behaviour of granular materials. All the above mentioned parameters were found to have a significant effect on the stress-strain behaviour of granular materials. Biaxial test simulations were also conducted to obtain basic granular material properties to derive analytical CPT solutions from continuum mechanics principles. Some of the DEM simulation results were found to be in good agreement with the analytical solutions that used a combined cylindrical-spherical cavity expansion method. Particle crushing was simulated during the cone penetration tests by replacing a broken particle with two new equi-sized smaller particles with mass conserved. The results showed considerable reduction in the tip resistance for the crushing model compared to the non-crushing model and this reduction increased as the confining stress increased.

Abstract:
Dense flows of grains are commonplace throughout natural and industrial environments, from snow-avalanches down the sides of mountains to flows of cereal down chutes as it is transported from one part of a factory to another. A ubiquitous feature in all of these flows is their ability to separate the different grain types when shaken, stirred, sheared or vibrated. Many flows are sheared through gravity and these flows are particularly efficient at segregating particles based on their size, with small particles percolating to the bottom of the flow and large particles collecting at the top. Within this mechanism, an asymmetry between the large and small particles has been observed, with small particles percolating downwards through many large particles at a faster rate than large particles rise upwards through many small particles. This alternative format thesis presents a revised continuum model for segregation of a bidisperse mixture that can account for this asymmetry. A general class of asymmetric segregation flux functions is introduced that gives rise to asymmetric velocities between the large and small grains. Exact solutions for segregation down an inclined chute, with homogenous and normally graded inflow conditions, show that the asymmetry can significantly enhance the distance for complete segregation. Experiments performed using a classical shear-box with refractive index matched scanning are able to quantify the asymmetry between large and small particles on both bulk and particle scales. The dynamics of a single small particle indicate that it not only falls down faster than a single large particle rises, but that it also exhibits a step-like motion compared to the smooth ascent of the large grain. This points towards an underlying asymmetry between the different sized constituents. The relationship between the segregation-time and the volume fraction of small grains is analysed, and solutions presented for the steady-state balance between segregation and diffusive remixing. These help to show the good agreement between the asymmetric model and experimental data. Segregation at the front of natural avalanches produces a recirculation zone, known as a `breaking size-segregation wave', in which large particles are initially segregated upwards, sheared towards the front of the flow, and overrun before being resegregated again. Solutions for the structure of this recirculation zone are derived using the asymmetric flux model, revealing a novel `lens-tail' structure. Critically, it is seen that a few large particles starting close to the bottom of the flow are swept a long way upstream and take a very long time to recirculate. The breaking size-segregation waves highlight the important interplay between segregation and the bulk velocity field. The properties of flowing monodisperse grains are explored through experiments on a cone that produce a beautiful radial fingering pattern. Equations developed in a conical coordinate system reproduce the measured linear relationship between fingering radius and initial flux, whilst also predicting the slowing and thinning dynamics of the flow. Overall, these results illustrate the complex nature of the granular rheology and provide perspectives for future modelling of segregation in dense granular flows.

Abstract:
Granular materials are used in several industrial processes involving natural and man-made materials at a vast range of length scales, such as mining, extraction, and handling of rocks and sand, as well as in agricultural and pharmaceutical industry. They are also widely adopted in civil and military applications (e.g. earthquakes, penetration of projectiles, stress waves attenuation) because of their ability to dissipate energy and attenuate shock loading. However, despite the wide-spread use, the comprehension of their mechanical behaviour at high strain rates is still limited. The main aim of this research is to provide a better understanding of the mechanics of granular materials and to develop a combined experimental/numerical capability to characterise and simulate the effects of high velocity excitations on the boundaries of granular domains and the consequent motion and deformation at high rates of strain. The achievement of this goal requires the knowledge of both meso-structural properties (i.e. initial density, wetness and confinement conditions) and the effects of micro-scale parameters (i.e. grain sizes and shapes, grains microstructure) upon the behaviour of granular assemblies. For this reason, attention is initially focused on the development of novel algorithms capable of correctly representing real mesostructures of granular materials, and on the estimation of their Representative Volume Elements. Subsequently, high strain rate experiments are conducted for a comprehensive mechanical characterisation of different types of sand and to evaluate the effect of micro-scale phenomena and rate dependency on the mechanical response of granular materials subjected to impact loading. In particular, after having assessed the geometric characteristics of given granular media, modelling tools for the generation of numerical samples that are statistically representative of real granular materials are developed. Two new efficient algorithms for the geometrical packing of spheres, able to concurrently assign total number of particles and radii distributions, are proposed. Then, a novel Voronoi-based method is presented to model a wide range of particles shapes. The obtained polyhedral grains are proved to successfully reproduce the relevant microscopic features of many naturally occurring granular media. The statistically representative packings thus generated are then used in Discrete Element simulations, which are executed to help designing experiments for the characterisation of granular materials at the meso-scale and to establish the dimensions of the Representative Volume Element of the investigated sands to be used in large-scale laboratory tests and multiscale simulations. A comprehensive experimental campaign on both single grains and granular assemblies at meso-scale is executed to gain insight into the complex behaviour of granular materials subjected to high strain rates and to produce valuable data for future calibration and validation of rate dependent constitutive models. The adoption of ad-hoc sample sizes allowed for the achievement of an improved dynamic equilibrium condition and enhanced reproducibility of the results with respect to what existing in literature. Additionally, a deeper understanding of the role of particles fracture on the behaviour of granular materials is gained by exploiting a number of conventional (microscopy) and novel (sound measurements) experimental techniques for in-situ and post-mortem analysis of samples subjected to a wide spectrum of rates of deformation. Finally, once identified - through experiments - the central role of micro-scale phenomena (grains failure) on the mechanical response of sand, a new mass-conserving modelling methodology capable of capturing the grains comminution happening during dynamic loading of granular materials is introduced, thus extending the range of applicability of DEM to dynamic phenomena.

Abstract:
The Discrete Element Method (DEM) has been applied to numerical modelling of the bulk compression of low modulus particulates. An existing DE code for modelling the contact mechanics of high modulus particles using a linear elastic contact law was modified to incorporate non-linear viscoelastic contact, real containing walls and particle deformation. The new model was validated against experimental data from the literature and physical experiments using synthetic spherical particles, apple and rapeseed. It was then used to predict particle deformation, optimum padding thickness in a handling line and bulk compression parameters during oilseed expression. The application of DEM has previously been limited to systems of hard particles of high compressive and shear modulii with relatively low failure strain. Material interactions have therefore commonly been modelled using linear contact law. For high modulus particles, particle shape change resulting from deformation is a not a significant factor. Most agricultural particulates however deform substantially before failure and their interaction is better represented with non-linear hysteretic viscoelastic contact relationship. Deformation of geometrically shaped particles in DEM is usually treated as "virtual" deformation, which means that particles are allowed to overlap rather than deform due to contact force. Change to particle shape has not previously been possible other than in the case of particles modelled as 2-D polygons or where each particle is also modelled concurrently with an FE mesh. In this work a new approach has been developed which incorporates a non-linear deformation dependent contact damping relationship and a shape change while maintaining sufficient geometrical symmetry to allow the problem to be handled by the same DE algorithms as used for true spheres. The method was validated with available experimental results on impact behaviour of rubber and the variations with different damping coefficients were simulated for a selected fruit. A fruit handling process dependent on the impact process was then simulated to obtain data required in the design of a fruit processing line. Changes in shape of spherical synthetic rubber particles and rapeseeds under compression were predicted and validated with physical experiments. Images were taken and analysed using image processing techniques with 1: 1 scaling. The method on shape change entails a number of simplifying assumptions such as uniform stress distribution and homogeneous material properties and uniform material distribution when deformed, which are not observed in real agricultural materials and will tend to overestimate the true contact area between particles. In reality for fruits and vegetables, material redistribution is a complex process involving a combination of compaction and movement. However with the new method a better approximation of bed voidage (which standard DEM approaches underestimate) and stress were obtained in the compression of a synthetic material. This is a significant improvement on existing methods particularly with respect to stress distribution within a bulk particulate system comprising deforming elements where the size and orientation of contact surface between particles has a strong influence on the bulk modulus. The new model was used for prediction of mechanical oil expression in four oilseed beds. Similar patterns in the variation of the characteristic parameters were obtained as observed in existing experimental data. The data could not be matched exactly as the quantity and arrangement of seeds in the initial seedbeds were not the same as those used in the experimental work. However the DE model gave approximate oil point data for seedbeds with the same physical properties and initial conditions as in the experiment. This suggests that the new model may be a useful tool in the study of mechanical seed-oil expression and other agricultural particulate compression processes.
