The overall objective of thickened and paste tailings disposal has been stated many times: it is to thicken a slurry the point where non-segregating, will beach form sloping, sub-aerial deposit. The advantages this type scheme have include higher density, strength (including avoidance slimes pond), improved seismic resistance, better closure rehabilitation prospects lower compressibility). ai...

The present study is devoted to an approximate modeling for numerical simulation of flows past oscillating airfoils. In this study, it is shown that the harmonic oscillating objects can be studied by simple numerical codes that are not able to solve moving grids. Instead of using moving grid for the simulation of flowfield around an oscillating airfoil, this unsteady flow is solved on a fixed g...

Recent advances in experimental characterization techniques offer unique opportunities to evaluate mechanical properties of geomaterials. In this paper, authors introduce two such techniques that have significant potential to impact geomechanics community. The technique of using Instrumented indentation testing using nano-indenter to evaluate hardness and modulus of individual sand particles is...

Abstract The first introduction of fuzzy theory in the nineteenth century created room for continuous research and application various fields. Fuzzy set has been globally applied geotechnical engineering, this field continues to date. inference system is considered be one most popular techniques adopted resolve some geomechanical challenges faced both surface underground excavations. This paper...

Granular anisotropy is attributable to many complex behaviors of granular materials and reflects important microstructures at the grain scale, and should be fully considered towards the development of realistic constitutive models for such materials. In this paper, we present a study on the behavior of anisotropy using a three-dimensional Discrete Element Method (DEM). Isotropic packings of san...

The objective of the present project was to study how high temperatures affect the different mechanical parameters of chalks. The general result is that both cohesion and the hydrostatic yield stress are typically reduced about 20 % in going from 20 to 130 C, but the magnitude of this reduction may be chalk type dependent.
