Abstract
This study presents a 3-D particle simulation model based on the discrete element method for the weathering processes of geomaterials. We modeled their properties of swelling and shrinking by changing the diameter of spherical region which is consisting of clay minerals and several sand particles. A series of simulations of deformation of mudstone under wet-dry cyclic condition was performed so that the applicability of the proposed model can be validated.
