Effective Stress Based Large Strain Modulus Degradation Response of Fully Saturated Clean Sands
Bilge, Habib Tolga; Çetin, Kemal Önder (2015-9-11)
Current state of practice to assess ground response under seismic loading is mostly based on well-known and widely-used total stress-based equivalent linear assessment methodology, as part of which, mostly, strain compatible shear modulus and damping relationships need to be used. As implied by its name, "total stress", accumulation of excess pore water pressure which is a significant component of cyclic response, is not considered. Neglection of this component will produce unconservatively biased deformati...
Effective ultrasonication process for better colloidal dispersion of nanofluid
Mahbubul, I. M.; Saidur, R.; Amalina, M. A.; Elcioglu, E. B.; Okutucu Özyurt, Hanife Tuba (2015-09-01)
Improving dispersion stability of nanofluids through ultrasonication has been shown to be effective. Determining specific conditions of ultrasonication for a certain nanofluid is necessary. For this purpose, nanofluids of varying nanoparticle concentrations were prepared and studied to find out a suitable and rather mono-dispersed concentration (i.e., 0.5 vol.%, determined through transmission electron microscopy (TEM) analyses). This study aims to report applicable ultrasonication conditions for the disper...
Effective stress principle for saturated fractured porous media
Tuncay, Kağan (1995-12-01)
An effective stress principle for saturated fractured porous media is proposed based On the double-porosity representation. Both the solid grains and the fractured porous medium are assumed to be linearly elastic materials. The derivation employs volume averaging technique to obtain macroscopic scale expressions. Two parameters, the bulk modulus of the fractured medium and bulk modulus of the porous matrix, are introduced in the formulation. The final expression reduces to the one obtained by Blot and Willi...
Effective Stress and Shear Strength of Moist Uniform Spheres
Toker, Nabi Kartal; Culligan, Patricia J. (Wiley, 2014-05-01)
In continuum soil mechanics, the mechanical behavior of an element of soil is related to the effective stress, which is a measure of the average stress transmitted through the solid matrix in the form of contact stresses. In unsaturated soils, the coexistence of water and air within the soil pore space complicates this concept because the microscopic distribution of each fluid phase in soil pores cannot be known. Because it is thus not possible to physically measure effective stress in unsaturated soils, it...
