Abstract
The process of internal erosion of ¯ne particles from a soil has been modelled using two-dimensional discrete element analysis of assemblies of circular discs of various gradings. Maintaining a sample under constant stresses, finer particles have been progressively removed and the resulting deformations observed. The stability of the particle removal is related to the stress ratio which the sample is experiencing. The material is described by a model in which strength is controlled by state parameter - distance from the critical state line. As the grading is narrowed the critical state line rises, but as particles are removed the specific volume rises more rapidly and the material feels looser.
