The difference of sample preparation methods will directly lead to the structure sample, and mechanical response characteristics under external load be different. Based on conventional tests such as particle analysis, specific gravity, critical moisture content, consolidation test undisturbed loess from Xi’an, this paper focuses static triaxial consolidated drained shear undrained remolded loes...

The Yellow River alluvial silt has unique engineering properties and is unstable when encountering moisture. mechanical of subgrade can be impaired by the increase in moisture content due to rainwater infiltration, which a negative effect on traffic safety. To further reveal influence deformation characteristics silt, series monotonic cyclic triaxial tests were conducted with different contents...

Despite its widespread use as graft material in orthopaedic surgical procedures, morselized cancellous bone has not yet been well characterized from the standpoint of its mechanical properties. To accommodate the noncohesive nature of this loose particulate form of bone, a triaxial compression test apparatus commonly used in engineering soil mechanics was adapted for the testing of fresh-frozen...

The consequences of nuclear black holes for the structure and dynamics of stellar spheroids are reviewed. Slow growth of a black hole in a pre-existing core produces a power-law cusp, ρ ∼ r −γ , with γ ≈ 2, similar to the steep cusps seen in faint elliptical galaxies. The weaker cusps in bright ellipticals, γ ∼ < 1, may result from ejection of stars by a coalescing black-hole binary; there is m...

The laboratory tests for measuring the effects of small strain to the shear strength and maximum stiffness development of post-cyclic degradation of hemic peat are reviewed in this paper. A series of laboratory testing has been conducted to fulfil the objective of this research to study the post-cyclic behaviour of peat soil and focuses on the small strain characteristics. For this purpose, a n...

In this study we investigate the effect of prior seismic shaking on monotonic shear strength saturated Ottawa Sand 20/30. We perform a series stress-controlled undrained cyclic triaxial tests with different intensities intentionally without causing failure, followed by drainage excess pore pressure and an loading test to determine strength. The experimental data show that small moderate events ...

Liquefaction susceptibility of river channel deposit in Kolkata city is studied using laboratory cyclic triaxial tests. River deposit, which supports a large part rapidly growing urbanization city, mainly consists sandy soil with little amount silt. Cyclic tests have been performed on this sample varying relative density, confining pressure, and strain amplitude. Results are presented to show h...

This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...
