The use of numerical codes for simulating the propagation phase fast landslides requires definition constitutive relationships suitable description mechanical behaviour granular soils, under both solid and fluid conditions. In this paper, authors briefly illustrate a modelling approach interpreting material as bi-phasic continuum, according to which may behave like solid, quasi-static condition...

We study the influence of particle shape on the shear band formation in quasistatic granular media in biaxial compression test using two-dimensional Distinct Element Method (DEM). Elliptical-shaped particles are used to study the influence of particle shape. We also report an experimental verification to check the ability of DEM to model elliptical particles created by the clustering technique....

Granular soils are used in different areas of civil engineering due to their easy accessibility and low cost as a material. The sieve analysis method, which has been conducted rock physics measurements for many years, practicing determining the particle size distributions those materials. In this study, method based on image technique developed an alternative traditional distribution granular s...

The mechanical behavior of soils has been traditionally described using continuum-mechanics-based models. These are empirical relations based on laboratory tests of soil specimens. The investigation of the soils at the grain scale using discrete element models has become possible in recent years. These models have provided valuable understanding of many micromechanical aspects of soil deformati...

Due to the heterogeneous nature of granular soils and the involvement of many effective parameters in the geotechnical behavior of soil-foundation systems, the accurate prediction of shallow foundation settlements on cohesionless soils is a complex engineering problem. In this study, three new evolutionary-based techniques, including evolutionary polynomial regression (EPR), classical genetic p...
