IUTAM SYMPOSIUM ON MECHANICS OF GRANULAR AND POROUS
MATERIALS
SOLID MECHANICS AND ITS APPLICATIONS

Aims and Scope of the Series
The fundamental questions arising in mechanics are: Why?, How?, and How much?
The aim of this series is to provide lucid accounts written by authoritative research
ers giving vision and insight in answering these questions on the subject of
mechanics as it relates to solids.
The scope of the series covers the entire spectrum of solid mechanics. Thus it
includes the foundation of mechanics; variational formulations; computational
mechanics; statics, kinematics and dynamics of rigid and elastic bodies; vibrations
of solids and structures; dynamical systems and chaos; the theories of elasticity,
plasticity and viscoelasticity; composite materials; rods, beams, shells and
membranes; structural control and stability; soils, rocks and geomechanics;
fracture; tribology; experimental mechanics; biomechanics and machine design.
The median level of presentation is the first year graduate student. Some texts are
monographs defining the current state of the field; others are accessible to final
year undergraduates; but essentially the emphasis is on readability and clarity.

Preface
This volume constitutes the Proceedings of the IUT AM Symposium on
Mechanics of Granular and Porous Materials, held in Cambridge from 15th
to 17th July 1996. The objectives were:
1. To review existing experimental results and practical phenomena on the
flow and compaction of particulate media;
2. To review the current state of constitutive models, and their
implementation for predicting the macroscopic response.
3. Identification of the shortcomings of existing models and procedures in
understanding practical phenomena.
The Symposium brought together the research communities of solid
mechanics, materials science, geomechanics, chemical engineering and
mathematics to review current knowledge of the flow and compaction of
granular and porous media. The meeting emphasised the development and
use of constitutive laws to model practical processes such as mixing,
drainage and drying, compaction of metal and ceramic powders and soils,
and instabilities associated with these processes. A common theme was to
develop constitutive models from an understanding of the underlying
physical mechanisms of deformation and fracture.
It was particularly rewarding to find that the separate research communities
came together during the meeting and came to a consensus as to the main
mechanisms of deformation and failure of particulate and porous solids.
The Symposium consisted of forty lectures, all of which were invited and
accorded equal weight in the programme. In addition, two poster sessions
allowed for a further twenty presentations. Only the content of the lectures
is reflected in this volume. All the papers contained herein have been
reviewed to the standard of leading scientific journals.
The smooth running of the Symposium owes much to the initiative and
organisational skills of Jo Ladbrooke and Roxana Saadatnejad.
