This paper presents a review of the different models for concrete based on continuum damage theory, formulated at the Laboratoire de Mcanique et Technologie (Cachan, France). Derived in the framework of the thermodynamics of irreversible processes, each formulation is based on physical observation. and Zhang Wohua, 1993a, Dynamic analysis of rock engineering problems based on damage mechanics, Int. Symp on Application of Computer Methods in Rock Mechanics and Engineering, Xian Institute of Mining and Tech. The candidates will be able to derive and apply the equations of continuum mechanics in the following areas: Stress and strain analysis, deformation, work and energy, theory of elasticity, viscoelasticity, theory of plasticity, fluid mechanics and the basis for the constitutive equations. The mechanics of fluids and the mechanics of solids represent the two major areas of physics and applied mathematics that meet in continuum mechanics, a field that forms the foundation of civil and mechanical engineering. Although theoretical in character, this book provides a useful source of information for those dealing with practical problems relating to rock and soil mechanics a discipline which, in the view of the authors, attempts to apply the theory of continuum to the mechanical investigation of rock and soil media. Subsequently, it provides an enhanced continuum description of the mechanics of discrete materials, such as jointed rock, whose behaviour is governed by an internal length scale (e. joint spacing) Application of micropolar theory to the FEM analysis of layered and blocky materials was proposed by The elastic deformation of the solid rock is modelled according to the continuum theory of linear elasticity using threenoded triangular elements (Munjiza, 2004). Repulsive and frictional interaction Rock Mechanics and Rock Engineering x Overview Rock mechanics is the theoretical and applied science of the mechanical behaviour of rock and rock masses. Rock mechanics deals with the mechanical properties of rock and the related methodologies required for engineering design. The continuum theory of rock mechanics.

The theory of elasticity is used widely in rock mechanics to predict how rock masses respond to loads and excavation (surface and underground). Solid mechanics developed in the outpouring of mathematical and physical studies following the great achievement of Isaac Newton ( ) in stating the laws of motion, although it has earlier roots.

Chapter 1 THE CONTINUUM THEORY OF SOIL MECHANICS 1. 1 INTRODUCTION The most common structures which the geotechnical engineer may be required to design in soil and rock may be divided into three types of problems, namely: (1) the foundation and anchorage problems; (2) the slope and excavation problems; and (3) the earth pressure and retaining wall problems (Chen, 1975).

Mainly, stress concentration about holes of simple shape, using results from elasticity theory, e. , the problem of a circular hole in plane strain or plane stress (Kirsch equations), other shapes using complex variable theory applied mathematics, precomputer era. The damage tensor is built in the system of a continuum mechanics theory, and plays a role of transformation operator for the Cauchy stress. Since the damage tensor is introduced as a field variable in addition to stress and strain, one may need one more field. The mechanical behaviour of a rock mass is strongly affected by discontinuities such as faults and joints. In this paper, a damage mechanics theory is proposed which deals with some sets of discontinuities distributed in a rock mass, for example, joint systems. In this theory, the distributed. Continuum and Fluid Mechanics Continuum Mechanics is a means of studying the behaviour of materials by ignoring its particulate nature. A continuum is an area that can keep being divided and divided infinitely; no individual particles.
