Abstract
The dispersive behaviour of waves propagating in gradient-dependent and rate-dependent media is investigated analytically and numerically. Attention is focused on the proper modelling of dynamic strain localisation and the crucial role that dispersion plays in this. By considering the dispersive properties of a continuum and of a modelling in finite elements the effect of the discretisation on the localisation phenomenon can be quantified.
