A novel true triaxial test device with a high-temperature module for thermal-mechanical property characterization of hard rocks

European Journal of Environmental and Civil Engineering, 2022
Rock mechanical property testing under high-temperature true triaxial compression conditions is significantly important to understanding the stability of deep underground engineering rock masses where high temperature exists.

State space model of undrained triaxial test data for Bayesian identification of constitutive model parameters

Geotechnique, 2022
Soil constitutive model parameters can be identified from triaxial test data. The identification is frequently performed by fitting a constitutive model to triaxial test data from a purely statistical or probabilistic perspective based on an assumption ...

Study of shear behavior of granular materials by 3D DEM simulation of the triaxial test in the membrane boundary condition

, 2021
This paper studies the shear behavior of granular materials by using a three-dimensional (3D) discrete element method (DEM) simulation of the triaxial test. The experimental triaxial tests were conducted on glass beads samples for verification.
