Dilatancy and shear strength of sand at low confining pressures / T. Chakraborty in Journal of geotechnical and geoenvironmental engineering, Vol. 136 N° 3 (Mars 2010) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 136 N° 3 (Mars 2010) . - pp. 527-532 Titre : Dilatancy and shear strength of sand at low confining pressures Type de document : texte imprimé Auteurs : T. Chakraborty, Auteur ; R.

Fondations. Tunnels Résumé : Sand dilates with shearing at a rate that increases with increasing relative density (DR) and decreases with increasing effective confining stress (sigmac[prime]). The peak friction angle of a sand depends on its critical-state friction angle and on dilatancy. In this paper, we develop a simple correlation between peak friction angle, critical-state friction angle, and dilatancy based on triaxial compression and plane-strain compression test data for sand for a range of confining pressures from very low levels to approximately 196 kPa.
