The young history of the finite element method (FEM) reflects the dramatic increase of computing speed and storage capacity within a relatively short period of time. The history of the boundary element method (BEM) is still younger. Presently, intense scientific efforts aimed at extending the range of application of the BEM can be observed. More than 10 years ago, O.C. Zienkiewicz and his co-workers published the first papers on the coupling of FE and BE discretizations of subregions of solids for the purpose of exploiting the complementary advantages of the two discretization methods and reducing their disadvantages. The FEM has revolutionized structural analysis in industry as well as academia. The BEM has a fair share in the continuation of this revolution. Both discretization methods have become a domain of vigorous, world-wide research activities. The rapid increase of the number of specialized journals and scientific meetings indicates the remarkable increase of research efforts in this important subdolll.ain of computational ulechanics. Several discussions of this situation in the Committee for Discretization Methods ill Solid Mechanics of the Society for Applied Mathematics and Mechanics (GAMM) resulted in the plan to submit a proposal to the General Assembly of the International Union of Theoretical and Applied Mechanics (IUTAM) to sponsor a pertinent IUTAM Symposium. The endorsement of this proposal by the aforementioned GAMM-Committee and the cons ent of the International Association for Computational Mechanics (IACM) to co-sponsor such a scientific activity paved the way to the IUTAM/IACM Symposium on Discretization Methods in Structural Mechanics in Vienna, Austria, from June 5 to 9, 19SD. The main reason for the rather extensive topic of this Symposium, as reflected by its title, was the merger, at the request of IUTAM, of the original proposal by Prof. H.A. Mang, emphasizing the application of discretization methods to nonlinear structural mechanics, with a proposal by a group of members of the GAMM Committee for Discre tization Methods in Solid Mechanics, from the Federal Republic of Germany, around Prof. G. Kuhn, aimed at the application of the BEM to problems of structural mechanics. After some hesitation the undersigned organizers came to the conclusion that the advantage~ of this merger outweighed the disadvantages. The organization of the scientific program was guided by the intention to present an unbiased view on the capacity of the FEM, the BEM, and of combinations of the two methods as timely tools for the numerical solution of challenging problems in the field of structural mechanics. The active support by the members of the Scientific Committee, which is gratefully acknowledged, facilitated the realization of this intention. Apart from the organizers, the Scientific Committee consisted of the following members: VI J. Altenbach J. H. Argyris S. M. Atluri (Magdeburg/ GDR) (Stuttgart/FRG) (Atlanta/USA) N. Banichuk R. H. Gallagher P. Germain (Moscow/USSR) (Potsdam/USA) (Paris/France) Feng Kang M. Kleiber G. Maier (Beijing/ China) (Warsaw /Poland) (Milan/Italy) T. H. H. Pian A. Samuelsson A. G. Ugodchicov (Cambridge/USA) (Goteborg/Sweden) (Gorki/USSR) Y. Yamamoto (Tokyo/Japan) 81 scientists from 15 countries participated in the Symposium. The 42 oral presenta tions from leading experts in the area of computational mechanics gave a good impression of recent trends in discretization methods in structural mechanics. In some of these contri butions fundamental mathematical and/or mechanical problems related to these methods were treated. Some other contributions were devoted to the application of discretization methods to structural analysis of beams, plates, shells, etc. A large segment of the presen tations consisted of investigations of various mechanical phenomena, such as instability, vibrations, crack propagation, etc., by means of the FEM or the BEM. The book contains written versions of 40 out of the 42 oral presentations. The manuscripts were to be submitted approximately two months after the Symposium, al lowing the authors to consider comments from the discussion of their presentations. The organizers are deeply indebted to the following institutions and corporations for their generous financial support or for their effective help in the preparation and organi zation of the Symposium: International Union of Theoretical and Applied Mechanics (IUTAM) International Association for Computational Mechanics (IACM) Austrian Academy of Sciences Federal Ministry of Science and Research of the Republic Austria Daimler Benz AG, Stuttgart Siemens AG Austria Creditanstalt-Bankverein, Zweigstelle Rilkeplatz, Vienna Institute for Applied Mechanics of the University of Erlangen-Nuremberg Institute for Strength of Materials of the Technical University of Vienna VII The organizers would like to express their gratitude to Prof. O. Hittmair, President of the Austrian Academy of Sciences, for his opening address on behalf of the Academy, which was hosting the Symposium in its historical building, and to Prof. F. Ziegler, Member of the Bureau of IUTAM, and Prof. R.H. Gallagher, President of Clarkson University and Member of the IACM Exectutive Council, for their opening addresses on behalf of IUTAM and IACM, respectively. The organizers are also deeply indebted to their associates at the Institute for Ap plied Mechanics of the University of Erlangen-Nuremberg and the Institute for Strength of Materials of the Technical University of Vienna, respectively, for their help before, during and after the Symposium. Finally, as the editors of this book, they would like to thank the editorial staff of Springer-Verlag for the advice and the efforts concerning publication of these proceedings. G. Kuhn H. A.
