 			a) Experimental setup for the NGF model in one-dimensional shear.
 			The upper boundary is constant friction $\mu$ (stress controlled), or constant velocity $v_x$ (velocity controlled).
-			b) Rate dependence of critical-state till friction in laboratory experiments \citep[after][]{Iverson2010}, and influence of rate-dependence factor $b$ in Eq.~\ref{eq:g_local} on friction in the NGF continuum model with $\mu_\text{s} = 0.5$ and $\sigma_\text{n}' = 100$ kPa.
-			c) Mohr-Coulomb analysis of till samples in laboratory experiments and the NGF model.
