Distinct element modelling of the mechanical behaviour of intact rocks using voronoi tessellation model
This paper aims to study the mechanical behaviour and failure mechanism of intact rocks under different loading conditions using the grain based model implemented in the universal distinct element code (UDEC). The grain based numerical model is a powerful tool to investigate complicated micro-structural mechanical behaviour of rocks. In the UDEC grain based model, the intact material is simulat...
متن کاملElastic-plastic Analysis of Jointed Rock Mass Using Meshless Method
Analysis of rock masses with plenty of weakness planes and joints with numerical methods based on meshes encounters difficulties. In the analysis when even only a few meshes are involved, mesh generation can consume more time and effort compared to the construction and solution of the discrete set of equations. Continuous remeshing of the domain in order to avoid the break down of the calculati...
متن کاملOn the effect of grain size on rock behavior under cyclic loading by distinct element method
It is well-known that the mechanical behavior of rocks under cyclic loading is much different from static loading conditions. In most constructions, the load applied to structures is within dynamic ranges. That’s why a great deal of attention has been paid towards this field in order to identify the dynamic behavior of rocks in more details. Nevertheless, the nature of dynamic failure in rocks ...
متن کاملMembrane simulation analysis using Voronoi tessellation
The study of membranes and embedded proteins represents an advanced task in the field of molecular simulation. While nowadays a profound selection of sampling techniques, molecular topologies and theoretical approaches is available, the analysis of actual simulation data remains a difficult endeavour. For homogeneous lipid bilayer simulations, the calculation of the bilayer thickness or area pe...
متن کاملLaboratory and Numerical Modelling of a Jointed Rock Mass
Laboratory tests were performed on 54 large size specimens of jointed rock mass under uniaxial loading conditions. Based on this experimental study, a methodology has been suggested to estimate strength and tangent modulus of rock masses through a weakness coefficient. The methodology involves mapping of joints in the field and laboratory testing of intact rock specimens to arrive at rock mass ...
