Shearing tests with continuously increasing normal stress [PDF]

, 2006
In the conventional shearing tests the normal force or the normal stiffness are kept constant during the experiment. Sliding under constant normal load occurs in slopes if the environment is not changing during the process.

Development of triaxial compressive apparatus for neutron experiments with rocks [PDF]

Review of Scientific Instruments, 2022
Underground engineering for processes such as geological disposal of high-level nuclear waste, CO2 capture and storage, and mining and drilling for resources requires an understanding of the mechanical behavior of rocks at subsurface stress states, i.e., triaxial compressive stress.

Influence of the continuously increasing normal stress to the failure in case of shearing test [PDF]

, 2002
In a conventional shearing test the normal force or the normal stiffness is kept constant during the experiment. Sliding under constant normal load occurs in slopes if the environment is not changing during the process. The goal of this paper is to

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 ...

A simplified damage evolution relationship and deformation character¬istics of a pozzolanic lime mortar when subjected to unloading-reloading cycles in the pre-peak region

Fracture and Structural Integrity, 2019
Two series of uniaxial and triaxial compression tests including unloading-reloading cycles were performed under different confining press­ures, in order to study the stress-strain and the deformation behavior of a pozzolanic lime mortar subjected to ...
