Cavitation modelling in saturated geomaterials with application to dynamic strain localization

Abstract

A model to simulate cavitation phenomena in the pores of saturated porous media is developed. Such phenomena appear in connection with pore water traction, which may be observed during strain localization in dense sand samples or in dynamic fluid–structure interaction problems where the structure is made of geomaterials. The model makes use of an isothermal two‒phase flow approach. Numerical examples relating to strain localization are shown. © 1998 John Wiley & Sons, Ltd.
