Abstract
The dispersive behaviour of waves propagating in gradient-dependent an d rate-dependent media is investigated analytically and numerically. A ttention is focused on the proper modelling of dynamic strain localisa tion and the crucial role that dispersion plays in this. By considerin g the dispersive properties of a continuum and of a modelling in finit e elements the effect of the discretisation on the localisation phenom enon can be quantified.
