A multilaminate based model capable of predicting the behavior of granular material on the basis of sliding mechanisms and elastic behavior of particles is presented. The capability of the model to predict the behavior of sand under arbitrary stress paths is examined. The influences of rotation of the direction of principal stress axes and induced anisotropy are included in a rational way witho...

Triaxial consolidated drained, unconfined compression, and CBR tests have been conducted in order to study the stress-strain, strength, and volume change characteristics of fine sand specimens reinforced by polymeric fibers made from carpet wastes. The variables are aspect ratio (length/width) and weight percentage of the fibers. The results indicate that the peak strength and total volume chan...

An artiˆcial lightweight soil has been developed as a backˆll to reduce the earth pressure behind port and harbor structures. To reduce the unit weight lightening ingredient such as air foam or EPS beads is mixed within slurry of dredged soft clay, while cement is used as stabilizer to warrant compressive strength. This experimental study aims to characterize the strength and deformation proper...

We used computer simulations to study spontaneous strain localization in granular materials, as a result of symmetry breaking non-homogeneous deformations. Axisymmetric triaxial shear tests were simulated by means of standard three-dimensional Distinct Element Method (DEM) with spherical grains. Carefully prepared dense specimens were compressed between two platens and, in order to mimic the ex...

Abstract Membrane penetration is the term used to describe displacement of rubber membrane into spaces between cylindrical specimens during triaxial testing in consolidation stage. from elevated cell pressure stage might have a negative effect on interpretation stress-strain data and specimen volume calculations shearing To assist engineers making knowledgeable judgments, additional study neede...

The Bekenstein-Milgrom gravity theory with a modified Poisson equation is tested here for the existence of triaxial equilibrium solutions. Using the nonnegative least square method, we show that self-consistent triaxial galaxies exist for baryonic models with a mild density cusp ρ ∼ Σ r . Self-consistency is achieved for a wide range of central concentrations, Σ ∼ 10 − 1000M⊙pc , representing l...
