Abstract

In order to properly characterize the mechanisms of strain localization, the investigations of strain localization are needed both numerically and experimentally. The aim of this investigation is to provide insight into the phenomenon of strain localization in fluid saturated sands by means of numerical modelling. A constitutive model capable of describing the elastoplastic response of geomaterials including model nonassociativity is developed. The importance of the presence of fluid on the formation and evolution of strain localization in fully saturated 3D sand specimen are identified.
