Dilatancy equation of rockfill material under the true triaxial stress condition

Science China Technological Sciences, 2011
Rockfill material is widely used for construction of high rockfill dam due to its facility, economical cost, high strength and effective aseismatic property. It is provoked profoundly to propose a suitable constitutive model for a better application of this material.

Hysteresis, True-Triaxial Stress-Path and Pore Pressure Effects on Permeability

SPE/ISRM Rock Mechanics in Petroleum Engineering, 1998
Abstract All producing hydrocarbon reservoirs are subject to the earth's stress anisotropy and to any regional tectonic movements. In addition, the production of fluids from a reservoir formation reduces its pore pressure such that there is an increase in its effective stresses, and dynamic changes can also occur to the horizontal field ...

Petrophysical Properties Under True-Triaxial Stress For Hydrocarbon Recovery Prediction

SPE Permian Basin Oil and Gas Recovery Conference, 1998
Abstract The production of fluids from a reservoir often reduces pore pressure such that there is an increase in its effective stresses. During water flooding orgas injection the equilibrium rock stresses can also be altered in a similar dynamic manner. An understanding of these changes are of fundamental importance

Large stress reversals in true triaxial tests on cross‐anisotropic sand

International Journal for Numerical and Analytical Methods in Geomechanics, 2008
AbstractThe results of a series of true triaxial tests with stress paths involving large reversals under 3D conditions are presented. These tests were performed on medium dense Santa Monica Beach sand to provide experimental evidence for the rotational kinematic hardening hypothesis presented in a companion paper and to provide stress–strain and volume

True Triaxial Test of Rock Under Stress and Strain Rate Control

1988
The significance of true triaxial tests instead of conventional tests has been enhanced because of the need for generalized constitutive laws for geomaterials. To investigate the behavior of rock masses having restricted conditions for strains, tests of marble under strain rate control as well as stress rate control were performed using a specially ...
