Calculating the state parameter in crushable sands [PDF]

open access: yes, 2019
The state parameter (y) measures the distance from the current state to the critical state line (CSL) in the compression plane. The existence of a correlation between both the peak angle of shearing resistance ( # $ ) and peak dilatancy and y is central ...

Structural changes in latosols of the cerrado region: II - soil compressive behavior and modeling of additional compaction

open access: yesRevista Brasileira de Ciência do Solo, 2011
Currently in Brazil, as in other parts of the world, the concern is great with the increase of degraded agricultural soil, which is mostly related to the occurrence of soil compaction.

Loading rate effect on mechanical properties of an unsaturated silty sand [PDF]

open access: yesMATEC Web of Conferences, 2021
This paper presents the results of an experimental study on the effects of testing rate on stress-strain behavior and volumetric changes of soil. A series of suction-controlled triaxial tests has been performed on reconstituted specimens of a silty sand (
