Introduction
Porous materials can be both natural and artificial. Suchmaterials are encountered in a wide range of problems dealing with engineering, agriculture and science: Natural materials include soil and rock, and ar...

Introduction to Homogenization Analysis
We outline the essential features of a multiscale homogenization analysis. A problem of a one-dimensional elastic bar is given as an example.

Chapter
Long-Term Consolidation of Bentonite and a Homogenization Analysis of the Flow Field
Proposals for the geological disposal of heat emitting high-level radioactive wastes (HLW) have been put forward by many countries including Japan, Canada, Sweden, Switzerland, USA, Spain and others. The dispo...

Chapter
Virtual Work Equation, Variational Methods and Energy Principles
In this Chapter we consider the virtual work equation of a static problem and its relationship to the variational method and energy principle.

Chapter
Non-equilibrium Thermodynamics
We first review the principles of Classical Thermodynamics (see also Appendix D), and proceed to give an alternative formulation of Thermodynamics in the context of a true dynamical process.

Classical Theory of Diffusion and Seepage Problems in Porous Media
In this chapter we develop the coupled diffusion and seepage problem using the theory of mixtures. It is clearly understood that the diffusion problem is strongly linked to the seepage problem through the mass...

Chapter
Homogenization Analysis of Diffusion in Porous Media
We examine the problem of diffusion in a porous medium using a homogenization analysis (HA). Diffusion problems have important applications in environmental geosciences. We clarify the mechanism of diffusion, ...

Chapter
Introduction to Continuum Mechanics
The mechanics of a deformable body treated here is based on Newton’s laws of motion and the laws of thermodynamics.

Chapter
Classical Theory of Consolidation for Saturated Porous Media
Soil is a mixture of a solid phase, a liquid phase (i.e., water) and a gaseous phase. Saturated soil is a two-phase material which consists of a solid phase and a liquid phase. The formulation of a theory for ...

Chapter
Homogenization Analysis and Permeability of Porous Media
The Navier-Stokes’ (NS) equations can be used to describe problems of fluid flow. Since these equations are scale-independent, flow in the microscale structure of a porous medium can also be described by a NS ...

Computational modeling of the indentation of a cracked poroelastic half-space
The paper examines the computational modelling of the surface identation of a poroelastic half-space region which is weakened either by a cylindrical crack or a penny-shaped crack. The axisymmetric problems as...

Interface Plasticity and Micro-Crack Extension in an Inclusion Reinforced Solid
The transfer of stress between embedded fibres, inclusion type reinforcements and the surrounding matrix is achieved either by means of a bonding mechanism which can include chemical bonding and mechanical int...

Settlement of An Embedded Nuclear Waste Container Due to Creep of a Surrounding Geological Barrier
The paper discusses the influence of creep deformations of either engineered or natural geological barriers on the long term settlement of waste containers located within them. The paper describes, briefly, th...

Experimental Determination of Parameters Governing Heat-Induced Moisture Movement in A Clay Buffer
This paper discusses the experimental evaluation of the hygro-thermal parameters governing coupled heat and moisture movement within a moist clay buffer, which is developed as an engineered barrier for the iso...

Cracks at the Extremities of Cylindrical Fibre Inclusions
Studies on short fibre reinforced brittle composite materials indicate that the fibre ends act as crack initiators. An assessment of the behaviour of such cracks is of considerable interest to the adequate des...

Damage and Viscoplasticity Effects in the Indentation of a Polycrystalline Solid
This paper examines a problem related to the dynamic indentation of layer by a rigid punch. The layer consists of a polycrystalline material, such as ice, which exhibits elasticity with damage, delayed elastic...

Hygrothermal Performance of an Engineered Clay Barrier
A series of laboratory experiments was conducted to establish the heat-induced moisture movement in a bentonitic clay buffer. The buffer material is proposed as an engineered barrier to isolate a heat-emitting...

Body force loading of an annular adhesive contact region
This paper examines the problem related to the axisymmetric loading of an annular adhesive contact region between two identical isotropic elastic halfspaces. The paper focusses on the evaluation of the stress ...

On the expansion of a penny-shaped crack by a rigid circular disc inclusion
This paper examines the problem of the symmetric indentation of a penny-shaped crack by a smoothly embedded rigid circular thin disc inclusion. The analysis of the problem yields a system of triple integral eq...
