TL;DR: In this article, the role of particle rearrangement through interparticle slip and rotation and particle damage on primary compression on over 100 sands was examined to clarify the role that particle rearrangeement through particle rotation and slip/rotation was played in particle damage.

Characterization of Models for Time-Dependent Behavior of Soils
TL;DR: Different classes of constitutive models have been developed to capture the time-dependent viscous phenomena (creep, stress relaxation, and rate effects) observed in soils as mentioned in this paper, which are based on empirica.
Journal ArticleDOI
Creep characteristics of sands
TL;DR: In this paper, the creep characteristics of sands under constant principal stress differences of various stress levels which were experimentally obtained by drained triaxial compression tests were investigated. And the results of these tests are consistent with those predicted by the equations based upon the rheological model previously proposed by Murayama (1983).

Theory of undrained creep rupture of normally consolidated clay based on elasto-viscoplasticity
TL;DR: In this article, a theory of undrained creep rupture of normally consolidated clay is developed within the framework of an elasto-viscoplastic constitutive model, and the validity of the creep rupture theory is successfully verified based on the results of undrain triaxial creep tests on isotropically, normally consolidated samples of a natural clay.

Time-Dependent Mechanical Behavior of a Granular Medium Used in Laboratory Investigations
Hani Ghiabi,A.P.S. Selvadurai +1 more
TL;DR: In this article, an elastic-viscoplastic strain hardening constitutive model was proposed to predict the time-dependent response of an artificial granular medium consisting of glass beads to one-dimensional creep tests on both saturated and dry specimens.

Hyperbolic Stress-Strain Response: Cohesive Soils
TL;DR: In this article, the divergent concepts of a stability analysis, as compared with a load-deformation approach to soil mechanics, are shown to be compatible within the framework of a hyperbolic stress-strain relation.

General stress-strain-time function for soils
Awtar Singh,James K. Mitchell +1 more
TL;DR: In this paper, the authors show that there exist linear relationships between logarithm of strain rate and time for a given stress, and between the two at any given time, provided the creep stress level is between the practical limits of about 30% to 90% of the initial soil strength.

A constitutive equation for normally consolidated clay
Toshihisa Adachi,Masahisa Okano +1 more
TL;DR: In this article, the authors proposed a more general and realistic constitutive equation for fully saturated normally-consolidated clays by unifying the results of above two major approaches, namely, Roscoe's critical state energy theory for clays and Perzyna's theory of elasto/viscoplastic continuum and some empirical evidences.
