Conclusions
-
1.
A description of the limiting behavior of a clayey soil is permitted within the framework of the theory of plastic consolidation.
-
2.
The existence of a loading surface, the smoothness of the surface, and its normality to the vector of the increase in plastic deformation is confirmed experimentally.
-
3.
The significant effect of the third invariant stress parameter is observed, even under hydrostatic loading.
-
4.
The appearance of significant plastic anisotropy is established under nonhydrostatic loading.
-
5.
As we approach the limiting state, the loading surface shifts, breaking away from the coordinate origin of the space occupied by the principal stresses.
Further studies and treatment should be directed toward exposing the surface parameters as functions of the strain state for nonhydrostatic loading paths.
