Jointed Rock Failure Mechanism: A Method of Heterogeneous Grid Generation for DDARF

Elastic-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...

Microplane damage model for jointed rock masses

The paper presents a new microplane constitutive model for the inelastic behavior of jointed rock masses that takes into account the mechanical behavior and geometric characteristics of cracks and joints. The basic idea is that the microplane modeling of rock masses under general triaxial loading, including compression, requires the isotropic rock matrix and the joints to be considered as two d...

Simulation of hydraulic fracturing of jointed rock

This paper presents a modeling approach for three-dimensional simulation of hydraulic fracturing of jointed rock. The base for a successful computer based simulation for productive use is the ability to calculate the fractured volume with sufficient accuracy and efficiency. Especially in cases three dimensional effects have to be taken into account, the common commercial software tools in oil a...

A Deformation Method for Moving Grid Generation

In recent years several new moving grid methods have shown promising potential for applications in the numerical solution of time dependent differential equations. In this paper, a deformation method is reviewed and some new developments related to the method are presented. In particular, the method is applied to grid morphing and adaptive grid generation on domains with moving boundary. The me...
