Abstract: A theoretical framework to describe the behavior of natural clay is proposed in a new four-dimensional space, consisting of the current stress state, stress history, the current voids ratio, and a measure of the current ...

Abstract: This note presents the results of a study on the variation of the strength of geomaterials. A general isotropic strength criterion is proposed which unifies the peak strength and critical state (or steady state) strength ...

Abstract: Unlike that adopted in most existing compression models, the complete compression curve of reconstituted clays in the e − lnp′ space is S shaped. In this paper, an accurate S-shaped equation is proposed that is suitable ...
