Sergio Pellegrino – författare

Covering a wide range of structural concepts and presenting both relevant theories and their applications to actual structures, this book brings together for the first time lightweight structures concepts for many different applications and the relevant scientific literature, thus providing unique insights into a fascinating field of human endeavour. Evolved from a series of graduate courses taught by the authors at the University of Tokyo, the Institute of Space and Astronautical Science, the University of Cambridge and the California Institute of Technology, this textbook provides both theoretical and practical insights and presents a range of examples which also provide a history of key lightweight structures since the Apollo age. This essential guide will inspire the imagination of engineers and provide an analytical foundation for all readers.

The IUTAM-IASS Symposium on Deployable Structures: Theory and Applications was held on 6-9 September 1998 in the Department of Engineering, University of Cambridge. The Scientific Committee was appointed jointly by the two sponsoring organisations, the International Union for Theoretical and Applied Mechanics (IUTAM) and the International Association for Shell and Spatial Structures (lASS). Its membership was as follows: S. Pellegrino (UK, Chairman) C. R. Calladine (UK) L. B. Freund (USA) M. Geradin (Belgium) Y. Hangai (Japan) K. Kawata (Japan) B. Kroplin (Germany) S. ]. Medwadowski (USA) M. M. Mikulas (USA) A. Samartin Quiroga (Spain) F. P. ]. Rimrott (Canada) T. Tarnai (Hungary) The opening lecture of the Symposium was given by Professor C. R. Calladine. It was followed by seven lecture sessions on Concepts, Structural Mechanics, Reflectors, Deployable Structures in Nature, Design and Testing, Inflatable Structures, Simulation, plus a large interactive session during which posters and physical models were shown. A discussion of topics suggested by the participants took place during the closing session. There were 83 participants from 18 countries, and a total of 50 papers were presented. Financial support was generously provided by the International Union of Theoretical and Applied Mechanics (IUTAM). Additional support was provided by the British Council, the British National Space Centre (BNSC), and Kluwer Academic Publishers. We thank the members of the Scientific Committee for their willingness to referee to a high standard both the abstracts and the papers for the proceedings. Professor G. M. L.

This volume contains 37 papers contributed by former students, colleagues and friends of Professor Chris Calladine, to mark his retirement. Professor Calladine's research has ranged very widely across the fields of structural mechanics, with a particular focus on the plastic deformation of solids and structures and the behaviour of thin-shell structures, and molecular structures. A distinctive feature of his research has been a strong emphasis on rigorous formulations that provide both physical insights and accurate prediction of observed behaviour. This approach has led to major advances in many areas, and the papers included in this book give powerful illustrations going from the theory of structures (lightweight, adaptive, symmetric) to the design and analysis of shell structures, and the use of physical models in the study of DNA and bacterial flagella.

This Festschrift marks the retirement of Professor Chris Calladine, FRS after 42 years on the teaching staff of the Department of Engineering, University of Cambridge. It contains a series of papers contributed by his former students, colleagues, and friends. Chris Calladine's research has ranged very widely across the field of struc­ tural mechanics, with a particular focus on the plastic deformation of solids and structures, and the behaviour of thin-shell structures. His insightful books on Engineering Plasticity and Theory of Shell Structures have been appreciated by many generations of students at Cambridge and elsewhere. His scientific contri­ bution outside engineering, in molecular structures, is at least as significant, and he is unique among engineers in having co-authored a book on DNA. Also, he has been keenly interested in the research of many students and colleagues, and on many occasions his quick grasp and physical insight have helped a student, and sometimes a colleague, find the nub of the problem without unnecessary effort. Many of the papers contained in this volume gratefully acknowledge this generous contribution. We thank Professor G. M. l. Gladwell for reading through all of the contri­ butions, Mrs R. Baxter and Mrs o. Constantinides for help in preparing this volume, Godfrey Argent Studio for permission to reproduce Calladine's por­ trait for the Royal Society, and Dr A. Schouwenburg -from Kluwer- for his assistance. Horace R. Drew Sergio Pellegrino ix CHRIS CALLADINE SOME THOUGHTS ON RESEARCH c. R.
