We give here a close look to the development of pore pressures prior and after the onset of dynamic strain localisation in geomaterials. Three models are presented which allow to study cavitation observed during localisation in dense geomaterials. The physical background of these continuum models is highlighted and the resulting pore pressures are discussed together with their physical limits.

Abstract
We give here a close look to the development of pore pressures prior and after the onset of dynamic strain localisation in geomaterials. Three models are presented which allow to study cavitation observed during localisation in dense geomaterials. The physical background of these continuum models is highlighted and the resulting pore pressures are discussed together with their physical limits.
