Comparative Modelling of Shear Zone Patterns in Granular Bodies with Finite and Discrete Element Model
The evolution of patterns of shear zones in cohesionless sand for quasi-static earth pressure problems of a retaining wall under conditions of plane strain was analyzed with a discrete element method (DEM). The passive and active failure of a retaining wall was discussed. The numerical calculations were carried out with a rigid and very rough retaining wall undergoing horizontal translation, rotation about the top and rotation about the toe. The geometry of calculated shear zones was qualitatively compared with experimental results of laboratory model tests using X-rays and a Digital Image Correlation (DIC) technique, and quantitatively with corresponding finite element results obtained with a micro-polar hypoplastic constitutive model.
