Abstract: True-triaxial test data are fundamental in obtaining the constitutive laws of fiber-reinforced polymer (FRP)—confined concrete, especially concrete under nonuniform (passive) confinement. A new true-triaxial test system, ...

Abstract: The physical properties of shale reservoirs directly affect the form of shale gas and its preservation conditions, and an evaluation of these properties has great significance on the storage and exploitation of shale gas. ...
