Abstract

The nature puts no restriction and allows particles to behave freely and randomly. The soil particles deform when they are subjected to the loading, following a unique pattern. When the shear stress breaks down the original structure of a particulate mass during loading to a flow structure, steady state conditions occur. The soil deformation follows the Poisson process since the deformation follows the exponential order. The inter particle contact at the soil grains follows the concepts of simple friction. These revelations about soil behaviour paved way for a new concept called dynamic system based soil mechanics. In this model, the first order nonlinear differential equations are formed. The DSSM parameters for sand-silt mixtures under different drainage conditions decrease with increase in confining pressure. It is concluded that the applicability of this model varies with the gradation and grain size characteristics and sand silt mixtures.
