The Mohr-Coulomb friction angle of granular soils under different stress conditions
Keywords: True Triaxial Apparatus, plane strain conditions, the Mohr-Coulomb criterion
The friction angle ϕ′ describes the failure state of soil and it can be determined from the Mohr-Coulomb
criterion. In the classical approach, the friction angle ϕ′ is a physical feature of soil, and its value depends
only on the initial density. The paper aims at experimental verification of this assumption. The experimental
results show that the value of the friction angle ϕ′ also depends on the stress path that leads to the failure of
the sample. The experiments were performed in a classical triaxial apparatus and a true triaxial apparatus.
Series of compression tests for constant initial soil density, were performed for three different states of stress:
axisymmetric stress conditions, 3D stress conditions and plane strain conditions.
