On the modelling of stress-dilatancy behavior in weakly cemented sands
TL;DR: In this paper , a comprehensive study on the stress-dilatancy behavior of cemented sand and its modeling is presented, where the effect of confining pressure, relative density, and cement content on stress-dependency behavior are studied from the published experimental results and an additional series of experiments performed in this study.

On the compressibility and shear strength of natural clays
TL;DR: In this article, a new normalizing parameter called the void index is introduced to aid in correlating the compression characteristics of various clays, such as sedimentation compression curves for most, but not all, natural clays lie well above the corresponding intrinsic compression curves.

The general and congruent effects of structure in natural soils and weak rocks
S. Leroueil,P. R. Vaughan +1 more
TL;DR: In this article, the engineering properties of naturally occurring sedimentary and residual deposits which are usually treated in geotechnical engineering as ‘soils’ are reviewed, and it is shown that usually they have characteristics due to bonded structure which are similar to those of porous weak rock.

Elasto-plastic stress-strain theory for cohesionless soil with curved yield surfaces
TL;DR: An elasto-plastic stress-strain theory for cohesionless soil with curved yield surfaces is developed on the basis of soil behavior observed in laboratory tests as discussed by the authors, which is applicable to general three-dimensional stress conditions, but the parameters required to characterize the soil behavior can be derived entirely from results of isotropic compression and conventional drained triaxial compression tests.

Elastoplastic Stress-Strain Theory for Cohesionless Soil
Poul V. Lade,James M. Duncan +1 more
TL;DR: In this article, an elastoplastic stress-strain theory was developed for cohesionless soil based on the results of cubical triaxial tests on Monterey No.0 Sand.

Stress-deformation and strength characteristics of soil under three different principal stresses
Hajime Matsuoka,Teruo Nakai +1 more
TL;DR: In this paper, the authors expand the concept of three mobilized planes (compounded mobilized planes) among the three principal stress axes into a new postulate that a stress plane called "spatial mobilized plane" occurs in the three-dimensional stress space.
