Unified modeling behavior of rockfill materials along different loading stress paths

Soils and Foundations, 2022
Rockfill materials used for dam construction show obvious stress path dependency during construction process. The constitutive model for rockfill materials are mainly established based on conventional triaxial test.

Variation of Elastic Stiffness Parameters of Granitic Rock during Loading in Uniaxial Compressive Test

Applied Mechanics, 2023
Any rock mechanics’ design inherently involves determining the deformation characteristics of the rock material. The purpose of this study is to offer equations for calculating the values of bulk modulus (K), elasticity modulus (E), and rigidity modulus (
