The \emph{undrained plastic-bed} model by \citet{Tulaczyk2000b} was the first model to characterize subglacial till as a rate-independent material, where yield strength is solely dependent on compressive stress.
The model utilizes the relationship between porosity and effective normal stress in order to couple till strength with subglacial hydraulics, and successfully reproduces transient flow dynamics in ice-flow models \citep{Bougamont2011, vanDerWel2013, Robel2013, Gillet-Chaulet2016, Bougamont2019}.
-A common implementation is a regularized form where shear stress vanishes when shear-strain rates go to zero \citep{Schoof2006, Bueler2009, Schoof2010}
+A common implementation is a regularized form where shear stress vanishes when shear-strain rates go to zero \citep{Schoof2006, Bueler2009, Schoof2010}.
In these forms the shear stress is still limited to the Mohr-Coulomb value at higher rates \citep{Schoof2006, Bueler2009, Schoof2010}.
However, the Coulomb-frictional parameterizations do not describe the actual sediment deformation, but describe the basal friction felt by the flowing ice.
Shear deformation is known to deepen under increasing effective normal stress \citep{Fischer1997, Iverson1999, Boulton2001, Damsgaard2013}, and this may be a primary ingredient for growth of subglacial topography \citep[e.g.][]{Schoof2007}.
