Observable properties of E0 triaxial galaxies - A test for triaxiality

The Astrophysical Journal, 1987
It is shown that most triaxial galaxies oriented in space to appear as E0 galaxies should have observable rotation velocities. By projecting Levison and Richstone's (1987) triaxial models so that they look like E0s, it was found that v/sigma can be as large as 1.0.

The interpretation of advanced triaxial tests for the assessment of small strain stiffness [PDF]

E3S Web of Conferences
The measurement of small strain stiffness of soils is affected by the techniques and procedures used in advanced triaxial tests, including the connection between the internal load cell and the sample top platen, the resolution of the instrumentation, the

Experimental study of mechanical properties of highly-stressed rocks under true triaxial unloading conditions with different unloading directions

Shuiwen dizhi gongcheng dizhi
During the excavation process of deep rock masses, the surrounding rock stress field forms alternating zones of stress increase (loading zones) and stress decrease (unloading zones) near the excavation surface, which can easily trigger instability and ...

Comparison of Cyclic Triaxial Tests with Constant and Variable Cell Pressure

J
Cyclic triaxial tests are often used to evaluate the behavior of soils under seismic loads. The stress conditions imposed on a soil specimen during a cyclic triaxial test, however, are very different than those acting on an element of soil during an ...

Stiffness moduli in triaxial tests on a loess-sand mixture [PDF]

E3S Web of Conferences
Stiffness is one of the most important characteristics of geomaterials, and at the same time one of the most difficult to evaluate. It can be described by means of various stress-strain moduli, whose values strongly depend on the strain range and on the ...

Theoretical solution for the relationship between strength parameters of direct shear test and triaxial test

Yantu gongcheng xuebao
This paper analyzes the variation law of the Mohr's stress circle for normally consolidated soils in direct shear tests and triaxial compression tests. By comparing and analyzing the stress paths during the shearing process of the two tests, it is found ...
