Numerical Discrete Element Simulation Of Soil Direct Shear Test
One of the most common methods to measure soil mechanical properties (namely cohesion and internal friction angle) is direct shear box test. In this paper the development of a three-dimensional (3D) discrete element soil model for simulation of a cohesive soil’s direct shear test is presented. The aim was to calibrate the properties of the Hertz-Mindlin with bonding contact model available in E...
متن کاملA Discrete Modelling of Soil Fragments Transport by Runoff
We aim to model and visualize the evolution of the surface structure of a cultivated soil surface during rainfall. In this paper, we briefly present our model, based on an Extended Cellular Automaton, and the different simulated processes. Among these processes, we focus on runoff which is of high relevance as it drives the evolution of the soil surface structure by transporting anddepositing t...
متن کاملSensitivity Analysis of Stress and Cracking in Rock Mass Blasting using Numerical Modelling
Drilling and blasting have numerous applications in the civil and mining engineering. Due to the two major components of rock masses, namely the intact rock matrix and the discontinuities, their behavior is a complicated process to be analyzed. The purpose of this work is to investigate the effects of the geomechanical and geometrical parameters of rock and discontinuities on the rock mass blas...
متن کاملNumerical simulation of particulate materials using discrete element modelling
Discrete element method (DEM) is a numerical technique pioneered by Cundall for problems in rock mechanics where the continuity between the separate elements does not exist. Discrete numerical simulations with particles are currently used in several different scientific disciplines. The DEM is capable of handling a wide range of material behaviour, inter-body interaction force laws and arbitrar...
متن کاملSoil Reinforcement and Geosynthetics
In the context of sustainable development which is a balancing act between the fulfilment of human needs and the protection of the natural environment, the use of natural fibers such as coir in geotechnical applications is desirable. Reinforcing the soil with coir fibers/coir geotextiles is a cost effective solution to the ground/soil improvement problems. The effects of fiber parameters on the...
