The soil moisture content at shearing and other factors, including dry density grain size, influence its shear strength. This study investigated the effect of compaction size distribution on unsaturated Triaxial compression tests were performed in laboratory using modified triaxial apparatus silica sands No. 3 6 without fines with 20% to explore strength characteristics. Test samples compacted ...

Materials such as waste tire chips were widely used to improve the strength of soil. The objective of this study is to discuss the residual strength or steady-state behavior of sand-waste tire chip mixtures. A series of undrained monotonic triaxial compression tests were conducted on reconstituted saturated specimens of sand and sand-tire chip mixtures with variation in the tire-chip contents f...

The mechanical constitutive behavior of geomaterials is quite complex, involving pressure-sensitive yielding, differences in strength in triaxial extension vs. compression, the Bauschinger effect, dependence on porosity, and other factors. Capturing these behaviors necessitates the use of fairly complicated and expensive non-linear material models. For elastically isotropic materials, such mode...

The paper presents a new microplane constitutive model for the inelastic behavior of jointed rock masses that takes into account the mechanical behavior and geometric characteristics of cracks and joints. The basic idea is that the microplane modeling of rock masses under general triaxial loading, including compression, requires the isotropic rock matrix and the joints to be considered as two d...

Abstract Multi-axial compression of the mushy zone occurs in various pressurized casting processes. Here, we present a drained triaxial apparatus for semi-solid alloys that allow liquid to be drawn into or expelled from sample response isotropic compression. The rig is used measure pressure-dependent flow stress and volumetric during isothermal globular Al-15 wt pct Cu at 70 85 vol solid. Analy...

the purpose of this study is to survey cross section changes of the animal brain samples during the tension and compression tests and comparison of the experimental results for three animals: bovine, sheep, and rabbit. a linear elastic theory with considering the necking in tension and barreling in compression has been considered for brain tissue. bridgman method for tension and cross section u...

The study presents the test results of Completely Decomposed Granite (CDG) soil tested under drained triaxial compression, direct shear and simple tests. Special attention was focused on modification upper halve conventional Direct Shear Test (DST) to behave as freehead in movement along with vertical strain control during stage by using Geotechnical Digital System (GDS). show that Free (FDST) ...
