Preface
In the programme of the symposium was written:
"The International Union of Theoretical and Applied Me
chanics has taken the initiative to organize the sympo
sium. As the name of IUTAM implies, the organization
brings forward achievements within the field of theore
tical mechanics for application in science and engineer
ing.
According to the rules of IUTAM that only invited persons
can attend, all lecturers and participants have been ap
pOinted by the members of the scientific committee. To
facilitate contact among the attending persons, it has
been decided to restrict the total number to 85 persons
including the lecturers. Only one session is planned,
making it possible for everybody to attend all lectures.
Most scientists and engineers have realized that the
knowledge attained by extensive basic research is essen
tial in order to solve technological problems. In the
process of acquiring this knowledge we often fail to un
derstand that scientific progress is only achieved by two
main principles: (1) By studying the scientific litera
ture and applying or improving the theories in order to
predict behaviour and forces correctly, or (2) by re
jecting existing theories and developing new ways to
cope with the problem, resulting in a more differenti
ated and, hopefully, more exact theory.
Ice seems to be a simple material, but it is in fact so
complex and strange that it is only in the latest dec
ades that we have come to know some of the natural laws
governing its behaviour.
This symposium is one of the steps towards a better un
derstanding of the problems of ice".
The 25 papers presented at the symposium have now been
compiled in the present volume. The editQr has read
VI
through the papers and corrected obvious errors both in
orthography and syntax, but it has not been within my
scope to rewrite any part of the papers. All theories and
formulae presented by the authors are not in any way
checked or evaluated by the editor. The editor has
worked out a short resume of the discussions following
the presentation of the papers, partly based on notes
made during the discussion and partly derived from a re
cording made on magnetic tape throughout the discussion
part of the symposium.
As editor I wish to thank all the authors for their expert
contributions both in the written and verbal presentation
and their willingness to participate in the discussions.
I also wish to thank the International Union of Theore
tical and Applied Mechanics and its president professor
F. Niordsson for the initiative in arranging the symposium
and for the assistance offered to me during the planning.
At the Institute of Hydrodynamics and Hydraulic Engi
neering I wish to thank the professors H. Lundgren and
F.A. Engelund for their continued encouragement to do ice
research at the institute.
Finally I wish to thank the committee members for their
valuable contribution in proposing and selecting the au
thors and the participants and in assisting me to make
the final selection of topics to be presented.
For the professional assistance offered me by the staff
of the Institute of Hydrodynamics and Hydraulic Engineer
ing I particularly wish to thank Ms. E.B. Jensen, Ms.
L.K. Hansen and Ms. K. Dj¢rup for executing the secretari
al work with such care and accuracy.
