Creep of Engineering
Materials and Structures
Edited by
G. BERNASCONI and G. PIATTI
APPLIED SCIENCE PUBLISHERS This volume contains the proceedings
of a seminar organised by the ISPRA
establishment of the Joint Research
Centre of the European Commission.
The aims of the meeting were twofold,
firstly to describe the status of the creep
problem by examining the relationship
between continuum mechanics and
physical metallurgy and secondly to
promote the exchange of information
between people concerned with the
design of safe and reliable components
and structures.
Topics dealt with include creep
deformation, creep fracture mechanics,
creep damage, experimental aspects and
data collection, design procedure and
practical applications.

The seminar on which this book is based was organised by the Training and
Education Service and the Materials Science Division of the Joint Research
Centre (JRC), Ispra Establishment. It is part of a group of activities
(seminars, courses .. .) designed to encourage scientific and technical
exchanges at the European level in various specific sectors of great
topicality and importance. Bearing in mind these directives, which
correspond to one of the roles of the JRC, I should like briefly to describe
the themes of the seminar itself.
The industrial revolution of the last century, which has contributed
greatly to the progress of mankind, has also posed the problem of making
machines operated by heat (e.g. steam turbines) work at the highest
temperatures possible to obtain the greatest thermodynamic efficiency and
therefore the greatest yield. From this arose the problem of the heat
resistance of materials and structures (in other words the problem of'creep')
which did not exist in preceding centuries. Many years have passed and
creep has been studied in its various aspects (physical models, engineering
models, design, etc.) with considerable results, but the argument of
topicality always remains, as the operating temperature of machines and
structures continues to increase and designers always require more in the
way of stresses, resistance to the environment, performance, etc. It is
therefore undoubtedly useful to review the creep situation in its various
aspects from time to time and this is the aim of this book.
As scientific coordinator of the Ispra Seminar on Creep of Engineering
Materials and Structures, I have great pleasure in thanking the lecturers,
who have worked with us at Ispra and cooperated in the preparation of this
volume, and the participants at the seminar itself, for their presence and
their contributions. I would also like to say that a large contribution to the VI PREFACE
success of the seminar came from the help received from many people.
Continuous encouragement has been given by Professor G. R. Bishop,
Director of the Physics Department of the JRC, and Dr P. Schiller, Head of
the Materials Science Division. I am grateful to Mr B. Henry, Head of the
Training and Education Service, who organised the seminar itself with the
help of Mr S. Porrini. I would also like to thank my colleagues J. Donea,
R. Matera, G. Pellegrini, F. Rustichelli and J. Reynen for their help.
I would also like to express my gratitude to Professor G. Bernasconi of
Milan Polytechnic, who shares my great interest in the problems of
modellistics and heat resistance of materials, for his collaboration.
