Abstract

New developments in liquefaction modeling of angular soils using the Discrete Element Method (DEM) are presented. A technique is introduced to simulate the two-dimensional projection of angular grains by clumping a series of overlapping discrete circular elements of equivalent properties. Representative particles from different types of sands are scanned using a digital image analyzer, and the corresponding particle outlines are fitted accordingly for the DEM simulation. Particle assemblies of varying degrees of angularity are then subjected to simulated undrained cyclic shear conditions to assess their liquefaction susceptibility. The influence of grain morphology on the cyclic response is evaluated.
