A determination procedure of input parameters in elasto-viscoplastic finite element analysis
Atsushi Iizuka,Hideki Ohta +1 more
TL;DR: In this article, the determination procedure of input parameters to be used in an elasto-viscoplastic finite element computation is proposed, which is confirmed by the authors' experiences of analyzing the behavior of subsoil foundations.

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.

The influence of stress history and stress system on the stress-strain-strength properties of saturated clay
Toshiyuki Mitachi,Shigeru Kitago +1 more
TL;DR: In this paper, undrained triaxial compression and extension stress-strain behavior of a saturated remolded clay consolidated under K0 and isotropic stress conditions was investigated. And the authors proposed a new method of predicting undrained stressstrain behaviour of K0 consolidated clay by using the data obtained from isotropically consolidated undrained tests.

Development of a 3-D confinement-dependent dilation model for brittle rocks; Part 1, derivation of a Cartesian plastic strain increments ratios approach for non-potential flow rules
M. Rahjoo,Erik Eberhardt +1 more
TL;DR: In this paper, a non-potential flow rule is proposed to account for the directionality and 3-D confinement-dependency of dilation in brittle rock, where the authors present a new framework for understanding and modelling the 3D directionality of plastic deformations in Cartesian coordinates using what they call Plastic Strain Increments Ratio (PSIRs).

Nonlinear Analysis of Stress and Strain in Soils
James M. Duncan,Chin-Yung Chang +1 more
TL;DR: In this article, a simple, practical procedure for representing the nonlinear, stress-dependent, inelastic stress-strain behavior of soils was developed, based on the results of standard triaxial tests on plane strain compression tests involving primary loading, unloading, and reloading.

P. W. Rowe,L. Barden,I. K. Lee +2 more
TL;DR: In this paper, the authors examined the components of energy loss during a triaxial cell test and derived the stress dilatancy equation by inserting a modified cell pressure into the Bishop energy correction.
