The pore size and distribution of soil in the different stress path tests were studied by the optical microscope.
Keeping the minor principal stress and medium principal stress fixed, the loading in the direction of the major principal stress is a potential stress path in practical projects.
Analyzing the test results, the Duncan-Chang model can basically reflect the coarse grained soil's stress-strain relationship under the stress path of dam.
It is shown that the proposed model can much better simulate the effects of stress path and loading rate on the deformation and strength characteristics of sandy soil than the previous models.
The influence of loading distribution stress path and nonlinear deformation on foundation behaviour are studied in this paper.
Numerical modeling for sand′s double yield surfaces under stress path with increasing p
Effect of stress path circumgyration on shear modulus under small strain
It was indicated by the existing researches that the principal stress ratio in the stress path of rockfill DAMS kept constant during the period of dam construction.
The effect of different cyclic shear stress path under isotropic consolidation on the relationship of pore water pressure and accumulated energy dissipation is very little, itcan be ignored.
The constitutive model is developed to have a stress path-independent work-hardening parameter based on the modified plastic strain energy concept.
