Unified Identification of Viscous Instability in Both Solid and Liquid Clays

Abstract

AbstractWater-saturated clays are vulnerable to unstable creep if subjected to a relatively high shear stress, a phenomenon known as creep rupture for solid geomaterials and viscosity bifurcation for clay suspensions. By following Perzyna’s modeling ...Practical ApplicationsClay-water mixtures can suddenly weaken or fail when subjected to high shear stresses—a behavior known as creep rupture in solid clays or viscosity bifurcation in clay slurries. This study provides a consistent modeling approach and ...
