This book contains a collection of full papers presented at the ECCOMAS Multidisciplinary Jubilee Symposium -- New Computational Challenges in Materials, Structures, and Fluids, held in Vienna, Austria, February 18-20, 2008.

Computational challenges in materials, structures, and fluids, with a focus on multidisciplinarity and multi-scale analysis, are a hot topic in the engineering sciences (aerospace, civil, mechanical, etc.). Modern society in general and applied engineering sciences in particular are confronted with problems with levels of complexity never encountered before in the history of mankind.

The solution of scientific problems involving fluids together with solids and structures, not to forget materials, is of paramount importance in a technical world of rapidly increasing sophistication, referred to as the Leonardo World by the eminent German philosopher Jürgen Mittelstrass.

With this in mind, the ECCOMAS Managing Board decided to bring the principles of Applied Sciences into focus of the Jubilee Symposium by reconsidering the sources of relevant knowledge on processes occurring at different spatial and temporal scales. They are related to phenomena on different levels such as the nano-, micro-, meso-, and the macro level.

Zusammenfassung
This book contains 23 papers presented at the ECCOMAS Multidisciplinary Jubilee Symposium - New Computational Challenges in Materials, Structures, and Fluids (EMJS08), in Vienna, February 1820, 2008. The main intention of EMJS08 was to react adequately to the increasing need for interdisciplinary research activities allowing ef?cient solution of complex problems in engineering and in the applied sciences. The 15th anniversary of ECCOMAS (European Community on Computational Methods in Applied Sciences) provided a suitable frame for taking the afo- mentioned situation into account by inviting distinguished colleagues from d- ferent areas of engineering and the applied sciences, encouraging them to choose multidisciplinary topics for their lectures. The main themes of EMJS08 have a long tradition in engineering and in the applied sciences: materials, structures, and ?uids. The solution of scienti?c pr- lems involving ?uids together with solids and structures, not to forget the materials the structures are made of, is of paramount importance in a technical world of rapidly increasing sophistication, referred to as the Leonardo World by the eminent German philosopher Ju¨rgen Mittelstraß. More recently, the main themes of EMJS08 have gained considerable mom- tum, owing to signi?cant progress in nanotechnology. It enables resolution of a multitude of materials into their micro- and nanostructures. Covering aspects such as • Physical and chemical characterization • Multiscale modeling concepts, continuum micromechanics, and computational homogenization, as well as • Applications in various engineering ?elds the individual contributions to this book ?ow along different tracks of ?uids, materials, and structures.
