Volumetric Properties of Concrete under True Triaxial Dynamic Compressive Loadings
Journal of Materials in Civil Engineering, 2019AbstractAlmost all of the available test data for pressure–volumetric strain curves [equations of state (EoS)] of concrete are based on static triaxial tests and one-dimensional impact tests, for e...

Damage Evolution and Failure Behavior of Sandstone under True Triaxial Compression
Geotechnical Testing Journal, 2018Abstract In the present study, a series of conventional triaxial tests (CTTs) and true triaxial tests (TTTs) were performed on sandstone through a self-developed true triaxial testing system, which was combined with acoustic emission (AE) monitoring and X-ray computed tomography (CT) scanning technique to systematically study the damage ...

Deformability characteristics of a rock mass under true-triaxial stress compression
Geotechnical and Geological Engineering, 2006In this paper an experimental study was planned on rock mass model with three joint sets under triaxial and true-triaxial stress states to assess the influence of joint geometry and stress ratios on deformational behaviour of rock mass. The physical models were composed of three continuous orthogonal joint sets in which joint set-I was inclined at ...

Strength and failure characteristics of jointed marble under true triaxial compression
Bulletin of Engineering Geology and the Environment, 2019The rock structure and three-dimensional stress state play a vital role in the mechanical behaviour of rock masses. Here, a series of true triaxial compression tests (σ1 > σ2 > σ3) are conducted on jointed marble (50 × 50 × 100 mm3) containing a natural stiff joint, taken from the China Jinping Underground Laboratory (CJPL-II) project.

Strength and deformation characteristics of jointed media in true triaxial compression
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1978Abstract Laboratory triaxial compression tests to investigate the strength and deformation characteristics of jointed rocks under truly triaxial states of stress (σ 1 ≠ σ 2 ≠ σ 3 ) were conducted on an idealized model of a jointed rock in a specially designed loading arrangement.

Brittle fracture in two crystalline rocks under true triaxial compressive stresses
Geological Society, London, Special Publications, 2005Abstract We employed our new polyaxial cell to carry out true triaxial compression tests on dry (jacketed) rectangular prisms of two crystalline rocks, in which different magnitudes of the least and intermediate principal stresses σ 3 and σ 2 were maintained constant, and the ...

Deformability properties of model granular soils under true triaxial compression conditions
Moscow University Geology Bulletin, 2013The study presents a review of modifications to the design of true triaxial test apparatuses and described a new mixed boundary apparatus to study the stress-strain behavior of coarse-grained soil under true triaxial compression conditions. It was shown that the deviatoric component plays an important role in affecting the volumetric compression of ...

True triaxial cyclic behavior of concrete and rock in compression
International Journal of Plasticity, 1987Abstract Results from true triaxial cyclic tests on concrete are presented and compared with corresponding ones for dense rocks (mainly marbles) obtained under the same laboratory conditions. Common basic characteristics are confirmed regarding the essential effect of intermediate stress, the cataclastic mode of deformation under low confinement, the
