Preface
The General Assembly of the International Union of Theoreti
cal and Applied Mechanics decided in Cambridge, United King
dom, in 1982 to arrange the Symposium on Optical Methods in
the Dynamics of Fluids and Solids. This decision was stimu
lated by the fact that optical diagnostic methods are a more
and more important tool in experimental mechanics.
In contrast to the foregoing Symposium in Poitiers. 1976,
which was devoted exclusively to optical methods in the me
chanics of solids, it was a fruitful idea to bring together
during the present Symposium scientists engaged in optical
methods in the dynamics of all phases.
It was proposed by the International Scientific Committee
of the Symposium that contributions in experimental fluid
dynamics should deal with transition from laminar to turbu
lent flow, compressible fluid flow including high temperatu
re flow, non-equilibrium phenomena in fluid dynamics and the
interaction of fluid flow with solid boundaries and bodies.
As regard. the mechanics of solids, the contributions should
deal with the application of optical methods in the wave
propagation in shock loaded bodies, in phenomena connected
with the fracture mechanism, in nonstationary Vibrations of
elements and parts of systems and in nonstationary strains
in structures.
The International Scientific Committee preferred to avoid
invited lectures and in cooperation with the National Com
mittees of IUTAM called for contribution from individual
countries.
The scientific programme of the Symposium covered three
day~
The lectures and discussions showed clearly the state-of-the
art in this important field of experimental mechanics and
the progress which was achieved during the last years in the
development and utilization of optical methods in dynamice.
The social progra• • e comprised a concert of the world-known
Smetana Quartet on Tuesday, September 18th on the occasion
of the Year of Czech Music. Works by Czech composers Fr.X.
Richter, Leol ~ana~ek and Antonin Dvofak were performed. On
Thursday, Septe.ber 20th, a trip to the Konopiltl Castle and
a short sightseeing of Prague was organized. On Friday, in
the evening, a closing dinner for all participants and accom
panying persons was arranged at the Mirror Hall of the Libli
ce Castle.
The scientific part of the Symposium was closed on Friday in
the afternoon by a closing discussion of all participants.
The discussion was directed by the Chairman of the Symposium
and the members of the committee Prof.Merzkirch, Prof.Lagar
de and Dr. Trager had their cl08ing 8peeches. The problems of
the future develop.ent of optical methods and their applica
tion in mechanics of all phases were discussed. Hybrid pro
cesses based on detailed physical .odels supplemented by ex
peri.ental information were marked as extraordinaly prospec
tive.
The success of the Symposium would by impossible Without the
assistance of many people. My 8incere thanks are due to Sir
James Lighthill for his valuable advice regarding the 8cien
tific progra.me of the Symposium, to Prof.Jan Hult and Prof.
E.Becker for their support and deep interest in the organi
zation of the Sympo8ium. We are obliged to the members of
the International Scientific Co •• ittee and to the Local Or
ganizing Co.mittee for their work which contributed to good
scientific and 80cial level of thi8 event. My thanks belong
also to all authors whoee papers contributed to the success
of the Symposiu., to the Chair.an of the individual sessions
and to all other participants for their cooperation and
act~
ve interest.
The financial support of the IUTAH enabled to extend the num
ber of participants, especially from Asia and South A.erica.
The Symposium was organized under the auspices of the Czecho
slovak Academy of SCiences, which gave the nice Liblice Cast
le at our disposal.

An effective cooperation with Springer Publishing Company
during the preparation of the Proceedings was a pleasure for
ue and I wish to thank Hr.von Hagen for hie care of the pre
paration of this volume.
As the Proceedings are the collection of all papers presen
ted at this Symposium, we wish this book to stimulate fur
ther research in this important field of mechanics.
