Closure on a model for the mechanics of jointed rock
TLDR
In this paper, the authors present a mathematical model for the formation of a team of joined rocks, based on the idea that a particULAR JOINT was assumed to OCCUR at a given location.Abstract:
VASILESCU SUGGESTS THAT ROCK MECHANICS IS A NATURAL SCIENCE, ALTHOUGH THE AUTHOR IN THE CONTEXT OF THE PROBLEM BEING DISCUSSED, CONSIDERS THAT ROCK MECHANICS IS A BRANCH OF ENGINEERING, AND MATHEMATICALLY BASED METHODS OF DESCRIBING ROCK BEHAVIOR ARE NOT ONLY APPROPRIATE, BUT EXTREMELY POWERFUL. IN THE DESIGN OF EXCAVATIONS IN JOINT ROCK, ROCK MECHANICS IS VERY USEFUL. TERZAGHI OFTEN EXPRESSED THE VIEW THAT GEOLOGICAL UNCERTAINTIES LIMITED THE RELIABILITY OF ANALYSES IN WHICH A PARTICULAR JOINT WAS ASSUMED TO OCCUR AT A GIVEN LOCATION. THE MATHEMATICAL MODEL ENABLES THE EXTREME CASES TO BE STUDIED THROUGH PARAMETER STUDIES AND STATISTICAL METHODS. REPORTS ISSUED: A MODEL FOR THE MECHANICS OF JOINTED ROCK, RICHARD E.

Fundamentals of rock joint deformation
TL;DR: In this article, the deformation characteristics of rock joints under normal and shear loading were investigated by conducting loading/unloading and repeated load cycling tests on a wide variety of fresh and weathered joints in five different rock types.

Numerical modelling of discontinua
Peter Cundall,Roger D. Hart +1 more
TL;DR: Discrete element methods are numerical procedures for simulating the complete behavior of systems of discrete, interacting bodies as mentioned in this paper, and they can be classified into four classes: the distinct element method, modal methods, discontinuous deformation analysis and the momentum exchange method.

A solution method for planar and axisymmetric contact problems
TL;DR: The aim in this research is the development of a solution algorithm for analysis of general contact conditions which shall include the possibilities to analyse: contact between flexible-flexible and rigid--flexible bodies; sticking or sliding conditions; large relative motions between bodies; repeated contact and separation between the bodies.

On the numerical integration of interface elements
TL;DR: In this article, the impact of Gauss, Newton-Cotes, Lobatto and lumped integration schemes on the stress prediction in interfaces is investigated for three-dimensional linear and non-linear analyses.
