PREFACE
Recent advances in the field of fracture of engineering materials and structures have
increasingly indicated its multidisciplinary nature. This area of research now involves
scientists and engineers who work in materials science, applied mathematics and
mechanics, and also computer scientists. The present volume, which contains the
Proceedings of the Joint FEFG/lCF International Conference on Fracture of Engineering
Materials and Structures held in Singapore from the 6th to 8th of August 1991, is a
testimony of this multidisciplinary nature.
This International Conference was the Second Symposium of the Far East Fracture
Group (FEFG) and thus provided a unique opportunity for researchers and engineers in
the Far East region to exchange and acquire knowledge of new advances and applications
in fracture. The Conference was also the Inter-Quadrennial International Conference on
Fracture (ICF) for 1991 and thus appealed to researchers in the international arena who
wished to take advantage of this meeting to present their findings. The Conference has
brought together over 130 participants from more than 24 countries, and they represented
government and industrial research laboratories as well as academic institutions. It has
thus achieved its objective of bringing together scientists and engineers with different
backgrounds and perspectives but with .a common interest in new developments in the
fracture of engineering materials and structures.
This volume contains 4 keynote papers, 4 invited papers and 130 contributed papers. The
keynote papers cover a broad spectrum of research from the fracture of multi-layered
materials and brittle matrix composites to the fracture of polymers at interfaces and an
overview of recent Japanese research on ductile fracture. The invited papers and the
contributed papers, which have been grouped into 14 sections, also reflected a broad
range of research activities. The papers clearly indicated that research into the fracture of
composites, bimaterials and ceramics is still growing at a rapid pace. In particular,
interfacial fracture mechanics would continue to attract the interest of researchers for
many more years.
v
This International Conference would not have been possible had it not been for the kind
help and assistance from the Executive Committee members of the Far East Fracture
Group and the Council members of the International Congress on Fracture. Thanks are
due to the members of the International Honorary Advisory Committee and the
Organizing Committee for their generous help and advice throughout the preparations for
the Conference. The strong support provided by the secretarial staff of the Department of
Mechanical and Production Engineering, National University of Singapore, and the
encouragement from the Head of the Department, Associate Professor Poo Aun Neow,
are deeply appreciated.
The success of the Conference and the publication of this volume was not only the result
of the hard work of all the members of the Organizing Committee but also that of BAC
Printers for its editorial work, Applied Research Corporation for its help in the
Conference logistics, Diners World Travel for looking after accommodation and travel
related matters, and Elsevier Science Publishers for its advice on publishing
requirements. Finally, thanks are due to all the contributors for their careful preparation
of the manuscripts in camera-ready form. This method has its typographical limitations.
However, it is hoped that they will not distract the reader in any way.
