A Virtual Testing Approach for Honeycomb Sandwich Panel Joints in Aircraft Interior

By: Ralf Seemann

Virtual test methods can contribute to reducing the great effort for physical tests in the development of lightweight products. The present work describes an approach for virtual testing of sandwich panel joints based on the Building Block Approach and the Finite Elements Method. Building on a multitude of physical tests on sandwich materials and joints, adequate sub-models are developed, validated and synthesized to top-level models. The developed approach is eventually applied for the development of a novel sandwich panel joint.

Thin Liquid Films

Dewetting and Polymer Flow

By: Ralf Blossey

This book is a treatise on the thermodynamic and dynamic properties of thin liquid films at solid surfaces and, in particular, their rupture instabilities. For the quantitative study of these phenomena, polymer thin films (sometimes referred to as “ultrathin”) have proven to be an invaluable experimental model system. What is it that makes thin film instabilities special and interesting? First, thin polymeric films have an important range of applications. An understanding of their instabilities is therefore of practical relevance for the design of such films. The first chapter of the book intends to give a snapshot of current applications, and an outlook on promising future ones. Second, thin liquid films are an interdisciplinary research topic, which leads to a fairly heterogeneous community working on the topic. It justifies attempting to write a text which gives a coherent presentation of the field which researchers across their specialized communities might be interested in. Finally, thin liquid films are an interesting laboratory for a theorist to confront a well-established theory, hydrodynamics, with its limits. Thin films are therefore a field in which a highly fruitful exchange and collaboration exists between experimentalists and theorists. The book stretches from the more concrete to more abstract levels of study: we roughly progress from applications via theory and experiment to rigorous mathematical theory. For an experimental scientist, the book should serve as a reference and guide to what is the current consensus of the theoretical underpinnings of the field of thin film dynamics. Controversial problems on which such a consensus has not yet been reached are clearly indicated in the text, as well as discussed in a final chapter. From a theoretical point of view, the field of dewetting has mainly been treated in a mathematically ‘light’ yet elegant fashion, often making use of scaling arguments. For the untrained researcher, this approach is not always easy to follow. The present book attempts to bridge between the ‘light’ and the ‘rigorous’, always with the ambition to enhance insight and understanding - and to not let go the elegance of the theory.

Expert Level of Dental Resins - Material Science & Technology

Detailed discussion of the formulation, production and properties of dental resins and dental resin composites.

By: Ralf Janda

Resin materials are broadly used in dentistry for almost all indications, and they will gain even more importance in the future. Especially the increasing performance and efficiency of the CAD/CAM technology and 3D-printing open possibilities to use resins which were not used up to now in dentistry. Besides dentists, dental students or dental technicians, there are many other specialists such as researchers, material scientists, industrial developers or experts of adjoining professional disciplines who are technically engaged in dental resins. The "Expert Level" is the third book of the series "Dental Resins - Material Science & Technology". The "Expert Level" includes all information and data presented in the "Basic Level" and "Advanced Level" of this series, but enormously expands the knowledge base. From a total database of 8.198 references, 1.707 were selected and used for this textbook. It comprises more than 1,000 manuscript pages, 384 figures and 124 tables. The "Expert Level" describes very accurately and comprehensively all details of the material science and technology of dental polymers and composites. Furthermore, their production methods and applications are discussed in detail. Therefore, this book is a unique treatise of the complete present knowledge about dental resins and dental resin composites. This includes the discussion of the - raw/starting materials together with the explanation and presentation of their chemical structures and properties, their CAS Numbers and the names of the manufacturers. - amounts of the raw/starting materials usually used to formulate the finished products. - important material and toxicological properties of the starting materials and the finished products. - detailed description of the production processes of essential starting materials such as the syntheses of essential monomers, the silanization of inorganic fillers or the manufacturing of unfilled and filled splinter polymers. - detailed description of the formulation and the properties of the finished products. Furthermore, for many commercial endproducts rather detailed formulations as well as the exact production processes are described. All ISO standards that are relevant for dental resins are listed, too. Furthermore, many essential methods to test the mechanical, chemical and toxicological properties are also presented and explained. The "Expert Level" enables every scientist with a good chemical knowledge not only to understand how dental polymers function, but also to develop new and improved products.

A Jewish Communist in Weimar Germany

The Life of Werner Scholem (1895 – 1940)

By: Ralf Hoffrogge

Walter Benjamin derided Werner Scholem as a ‘rogue’ in 1924. Josef Stalin referred him as a ‘splendid man’, but soon backtracked and labeled him an ‘imbecile’, while Ernst Thälmann, chairman of the Communist Party of Germany (KPD), warned his followers against the dangers of ‘Scholemism’. For the philosopher and historian Gershom Scholem, however, Werner was first and foremost his older brother. The life of German-Jewish Communist Werner Scholem (1895–1940) had many facets. Werner and Gerhard, later Gershom, rebelled together against their authoritarian father and the atmosphere of national chauvinism engulfing Germany during World War I. After inspiring his younger brother to take up the Zionist cause, Werner himself underwent a long personal journey before deciding to join the Communist struggle. Scholem climbed the party ladder and orchestrated the KPD's ‘Bolshevisation’ campaign, only to be expelled as one of Stalin's opponents in 1926. He was arrested in 1933, and ultimately murdered in the Buchenwald concentration camp seven years later. This first biography of Werner Scholem tells his life story by drawing on a wide range of original sources and archive material long hidden beyond the Iron Curtain of the Cold War era. First published in German by UVK Verlagsgesellschaft as Werner Scholem - eine politische Biographie (1895-1940), Konstanz, 2014.
