Typesetting: Camera ready by authors SPIN: 10529284 PREFACE The IUTAM Symposium on Constitutive Relation in High/Very High Strain Rates (CRHVHSR) was held October 16 - 19, 1995, at Seminar House, Science University of Tokyo, under the sponsorship of IUTAM, Japan Society for the Promotion of Science, The Commemorative Association for the Japan World Exposition (1970), Inoue Foundation for Science, The Japan Society for Aeronautical and Space Sciences, and Science University of Tokyo. The proposal to hold the symposium was accepted by the General Assembly of IUTA M held in Haifa, Israel, in August 1992, and the scientists mentioned below were appointed by the Bureau of IUTAM to serve as members of the Scientific Committee. The main object of the symposium was to make a general survey of recent developments in the research of constitutive relations in high and very high strain rates and related problems in high velocity solid mechanics, and to explore further new ideas for dealing with unresolved problems of a fundamental nature as well as of practical importance. The subjects covered theoretical, experimental, and numerical fields in the above-mentioned problems in solids, covering metals, polymers, ceramics, and composites. Emphasis was given to the following fields: 1. Material characterization of solids in high velocity deformation, experimental techniques, typical data obtained by these techniques, modeling, and constitutive relations 2. Strain rate dependent elasto-visco-plastic stress waves 3. Crack initiation, propagation, and dynamic fracture toughness 4. Dynamic stress concentration 5. Structural dynamics in impact and constitutive relations of solids 6. Impact related problems These research fields were covered in 28 invited papers, and in 16 scientific sessions chaired by the invited specialists. As indicated in the scientific program, two papers could not be presented orally by their authors. Participants, numbering 47, came from 12 countries (Austria, China, France, Germany, Japan, Korea, Poland, Romania, Russia, Sweden, UK, and USA). Discussions ranged from the microscopic level of dislocation theory to the macroscopic behavior of engineering materials and structures. From the standpoint of science, technology, v VI and friendly exchange of opinions during social events, the aims of the IUTA M symposium were satisfactorily achieved. With advice and suggestions provided by IUT AM, the Local Organizing Committee was responsible for planning meetings, for social activities, and for editing the proceedings. The members of the International Scientific Committee and the Local Organizing Committee are listed below. We appreciate the contributions made by the following organizations: IUTAM, Science Council of Japan, Japan Society for the Promotion of Science, The Commemorative Association for the Japan World Exposition (1970), Inoue Foundation for Science, The Japan Society for Aeronautical and Space Sciences, and Science University of Tokyo. We express our sincere thanks to the IUTAM Officers Prof. L. van Wijngaarden, Prof. P. Germain, Prof. B.A Boley, and Prof. F. Ziegler and to former officers Sir J. Lighthill and Prof. W. Schielen for their valuable guidance and cooperation; to the Representatives of the National Committee for Theoretical and Applied Mechanics of the Science Council of Japan, especially Prof. I. Imai, Prof. Y. Yamamoto, and Prof. T. Tatsumi, for valuable guidance and arrangements; to the members of the Scientific Committee and the Local Organizing Committee; to all participants and all supporting members for their hearty cooperation in carrying out the meeting; and to Springer-Verlag Tokyo for publishing the record of scientific progress made by the symposium.
