Polymer composites were introduced for the aerospace industry as
light, strong, stiff materials, and adopted by the construction and
automobile industries, among others. Meanwhile, composite materials
have been introduced to fulfill the uses that these conventional
materials could not, such as in extreme environments. The research
for new composites includes not only new polymer systems, but
metals, ceramics and intermetallic systems as well. This volume
contains a selection of recent work by leading researchers in
micromechanics on the topics of prediction of overall properties of
elastic, perfectly bonded systems, problems associated with
inelastic deformation of the phase, debonding at interfaces and
growth of distributed damage. Many familiar aspects of mechanical
behavior, such as fatigue, fracture, strength and buckling, etc.
have been reexamined and adapted for these new systems.
The field of composite materials has seen substantial development
in the past decade, New composite systems are being continually
developed for various applications. Among such systems are metal,
intermetallic, and superalloy matrix composites, carbon-carbon
composites as well as polymer matrix composites. At the same time,
a new discipline has emerged of active or smart materials, which
are often constructed as composite or heterogeneous media and
structures. One unifying theme in these diverse systems is the
influence that uncoupled and coupled eigenfields or transformation
fields exert on the various types of overall response, as well as
on the respective phase responses. Problems of this kind are
currently considered by different groups which may not always
appreciate the similarities of the problems involved. The purpose
of the IUTAM Symposium on Transformation Problems in Composite and
Active Materials held in Cairo, Egypt from March 10 to 12, 1997 was
to bring together representatives of the different groups so that
they may interact and explore common aspects of these seemingly
different problem areas. New directions in micromechanics research
in both composite and active materials were also explored in the
symposium. Specifically, invited lectures in the areas of inelastic
behavior of composite materials, shape memory effects, functionally
graded materials, transformation problems in composite structures,
and adaptive structures were delivered and discussed during the
three-day meeting. This book contains the printed contributions to
the IUTAM Symposium.
This book contains papers contributed to the IUTAM Symposium on
Transformation Problems in Composite and Active Materials which was
held in Cairo, Egypt in March 1997. The chapters address uncoupled
and coupled transformation problems in composite and smart
materials and their structures. The book is organized into six
sections covering the following subjects: inelastic behaviour of
composite materials, shape memory effects, functionally graded
materials, transformation problems in composite structures,
adaptive structures, and elasticity issues. Although the field of
composite materials has seen substantial development in the past
two decades, new composite systems are continually being developed
for various applications. Among such systems are metal,
intermetallic, and superalloy matrix composites, carbon-carbon
composites, and polymer matrix composites. The field of smart
materials, on the other hand, is relatively new, but has also seen
important developments recently. These two seemingly different
fields have often been addressed in separate books, journals, and
technical meetings. The present book realizes and addresses the
similarities of the uncoupled and coupled transformation fields
involved in both composite and smart materials. Outstanding
researchers from the different groups active in mechanics of
composite and smart materials have contributed papers which explore
the common aspects of these materials and new directions in
micromechanics research in both areas. Researchers active in the
areas of mechanics of composite and smart materials will find this
book very useful in addressing recent developments in these areas.
