Numerical Investigation on the Reference Crushing Stress of Granular Materials in Triaxial Compression Test
Particle crushing dominates the deformation behaviour of granular materials under significantly high compressive and shear stress. A proposed constitutive model has been verified to predict crushing behaviour of granular materials with different crushability and adopted one kind of reference crushing stress. It is noted that no positive dilatancy of granular material in triaxial test occurs onc...
متن کاملInvestigation of Stress-Strain Behavior of Plastic Concrete Using Monotonic Triaxial Compression Tests
In this paper, the mechanical behavior of plastic concrete being used in the cut-off walls of earth dams has been studied. To do the task, triaxial compression tests on the specimens in various ages and mix designs under different confining pressures have been done and the stress-strain behavior of such materials and their strength parameter changes has been experimentally investigated. It has ...
متن کاملQuasi-static fault growth and cracking in homogeneous brittle rock under triaxial compression using acoustic emission monitoring
This paper describes the localization of deformation acceleration in the period prior to dynamic failure in hornblende schist rock under triaxial compression using acoustic emission (AE) monitoring. Rather than stabilize the failure process by controlling axial stress to maintain a constant rate of AE (for monitoring AE hypocenters) as in previous works [e.g., Lockner et al., 1991], we have ins...
متن کاملbehavior of rockfill materials in triaxial compression testing
this paper studies thoroughly and deeply the results of about one hundred triaxial compression tests on thirty types of rockfill materials. the materials are categorized in accordance with their particles shape (angular / rounded) and gradation characteristics. the main tool of the study is the hyperbolic model developed by duncan and chang. the focus of the study is on the variations of deform...
متن کاملstrength evaluation of wet reinforced silty sand by triaxial test
conventional investigations on the behavior of reinforced and unreinforced soils are often investigated at the failure point. in this paper, a new concept of comparison of the behavior of reinforced and unreinforced soil by estimating the strength and strength ratio (deviatoric stress of reinforced sample to unreinforced sample) at various strain levels is proposed. a comprehensive set of labor...
