Abstract

This exposition is dedicated to Professor Gert Gudehus on his 80\(^\mathrm{th}\) Birthday, who was among the first to realise the potential of GSH, presciently and more clearly than we did. In what follows, we shall first generalising the notion of rate-independence to invariance under a scale transformation in time. We then demonstrate this invariance of GSH (granular solid hydrodynamics) at typical shear rates of soil-mechanical experiments, for both slowly varying and suddenly changing rates, and in the presence of shear bands. Scale invariance is lost, and rate-dependence appears, at higher shear rates such as given in chute flows.
