Stability of Undrained Deformation of Fluid-saturated Geo-materials
The presence of pore fluids in geomaterials can alter deformation processes and facilitate or delay material failure. Dilation/contraction of geomaterials in the course of inelastic undrained deformation causes a reduction/increase in pore pressure altering the effective compressive stress. This results in an increase/decrease in shear stress that can be sustained by the material over the corre...
متن کاملHigh Resolution Cat Imaging of Fractures in Consolidated Materials
High resolution measurements of fracture aperture of granite and sandstone rocks were performed using CAT scanner. The aperture distribution was statistically characterized for future experimental and numerical studies on single and multiphase flow and transport. The fracture aperture can be measured in-situ and nondestructively with CAT-scanning. The minimum pixel size is 0.27 x 0.27 mm, but f...
متن کاملEffective Thermal Expansion Property of Consolidated Granular Materials
Thermally-assisted compaction of granular materials is of keen interest in many engineering applications. A proper estimation of the material behavior of compacted granular materials is contingent upon the knowledge of microstructure formation, which is highly dependent on the bulk material properties and processing conditions, during the deformation stage. Originating from the pair interaction...
متن کاملStudying the effect of inherent anisotropy on undrained behavior of sand-silt mixtures
In some situations, dams need to be built on non-rock alluvial grounds such as sand and sand-silt deposits. Therefore, undrained behavior and strength of silty sands are of great importance. One of the critical factors in studying the behavior of sand-silt mixtures is inherent anisotropy, a natural soil characteristic that depends on its texture and is independent of the soil's initial stress s...
متن کاملUltrasound propagation in wet and airless non-consolidated granular materials.
This paper deals with an experimental description of the acoustic behaviour of non-consolidated granular materials submitted to static force. The aim of this work is to investigate the effect of a small amount of an interstitial fluid on the acoustic propagation. Measurements of the velocity and of the transmission of the coherent wave are performed for different values of the applied force. It...
