A Three-Dimensional Constitutive Model for Rocks Based on a Strain-Dependent Elastic Modulus

Lithosphere, 2022
Our research group previously proposed a simple two-dimensional (2D) constitutive model for rocks to simulate not only the axial stress–axial strain relationship, but also the axial stress–lateral strain relationship, with few complicated equations ...

Loading rate dependence of permeability evolution in porous aeolian sandstones [PDF]

, 2004
Mechanical properties of rocks are characterized by their notable dependence on the applied deformation rate. However, little is known about the strain rate dependence of fluid flow properties since most laboratory tests are conducted using a single ...

PERMEABILITY ANISOTROPY OF SHIRAHAMA SANDSTONE UNDER TRUE TRIAXIAL STRESSES

Doboku Gakkai Ronbunshu, 2002
Anisotropic stresses may induce anisotropic permeability of rocks. The present study aims at establishing the relation between permeability tensor and principal stresses for Shirahama sandstone within the pre-yield range. The effects of three principal stresses on the permeability are experimentally investigated using a Mogi-type true triaxial ...
