Abstract: Materially objective, rate‐type constitutive relations are presented for creeping soil. The soil is treated either as a non‐Newtonian viscous fluid or a saturated mixture of an inviscid interstitial fluid and a non‐Newtonian ...

Abstract: A constitutive model for soils and interfaces involved in creeping natural slope is proposed. It is based on the hierarchical single-surface plasticity and viscoplasticity approaches and allows for factors such as elastic, ...
