Numerical Simulations of Laboratory Experiments for Determining the Post-yielding Mechanical Parameters of Soil and Rock

ABSTRACT: The mechanical parameters of constitutive equations for soil and rock can be determined by laboratory experiments in which a cylindrical specimen is commonly tested under uniaxial and triaxial compressive conditions. The distribution of stress in the specimen during the tests must be kept uniform and homogeneous. In this paper, numerical simulations are carried out to determine the di...

Sensitivity 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...

Motion-based threat detection using microrods: experiments and numerical simulations.

Motion-based chemical sensing using microscale particles has attracted considerable recent attention. In this paper, we report on new experiments and Brownian dynamics simulations that cast light on the dynamics of both passive and active microrods (gold wires and gold-platinum micromotors) in a silver ion gradient. We demonstrate that such microrods can be used for threat detection in the form...

Pore-scale controls on calcite dissolution rates from flow-through laboratory and numerical experiments.

A combination of experimental, imaging, and modeling techniques were applied to investigate the pore-scale transport and surface reaction controls on calcite dissolution under elevated pCO2 conditions. The laboratory experiment consisted of the injection of a solution at 4 bar pCO2 into a capillary tube packed with crushed calcite. A high resolution pore-scale numerical model was used to simula...
