Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - For many years the Austrian tunneling industry has demanded that research is urgently required to establish a theoretical basis for the New Austrian TUnneling Method and to assist site engineers in the often difficult day to day decisions. In particular it was felt that numerical models need to be improved considerably in order to be able to act as useful tools in predicting soil/rock mass behavior during tunneling. The required improvement not only refers to the quality of the models but also to their ease of use. As long as an experienced modeler is required to spend days in preparing the input and in interpreting the results the models will not be useful at the tunnel site. It is heartening therefore that a group of scientists in Austria has come together to attempt to tackle this challenging task. The initiative has been supported in a number of ways by the Austrian tunneling industry. All Aus trian companies associated with tunneling sent representatives to the man agement advisory board, which ensured that the research carried out in the project, was of benefit to the industry. The Austrian Geomechanics Society sponsored the project with a considerable amount, which was mainly used to cover site costs. HL-AG and OSAG, as well as the joint ventures allowed access to tunnel sites thereby making it possible to test new developments.

Buch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - This book discusses the introduction of isogeometric technology to the boundary element method (BEM) in order to establish an improved link between simulation and computer aided design (CAD) that does not require mesh generation. In the isogeometric BEM, non-uniform rational B-splines replace the Lagrange polynomials used in conventional BEM. This may seem a trivial exercise, but if implemented rigorously, it has profound implications for the programming, resulting in software that is extremely user friendly and efficient. The BEM is ideally suited for linking with CAD, as both rely on the definition of objects by boundary representation. The book shows how the isogeometric philosophy can be implemented and how its benefits can be maximised with a minimum of user effort. Using several examples, ranging from potential problems to elasticity, it demonstrates that the isogeometric approach results in a drastic reduction in the number of unknowns and an increase in the quality of the results. In some cases even exact solutions without refinement are possible. The book also presents a number of practical applications, demonstrating that the development is not only of academic interest. It then elegantly addresses heterogeneous and non-linear problems using isogeometric concepts, and tests them on several examples, including a severely non-linear problem in viscous flow. The book makes a significant contribution towards a seamless integration of CAD and simulation, which eliminates the need for tedious mesh generation and provides high-quality results with minimum user intervention and computing.

Buch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - The book presents the state of the art in isogeometric modeling and shows how the method has advantaged. First an introduction to geometric modeling with NURBS and T-splines is given followed by the implementation into computer software. The implementation in both the FEM and BEM is discussed.

Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - This is a sequel to the book 'Programming the Boundary Element Method' by G. Beer published by Wiley in 2001. The scope of this book is different however and this is reflected in the title. Whereas the previous book concentrated on explaining the implementation of a limited range of problems into computer code and the emphasis was on programming, in the current book the problems covered are extended, the emphasis is on explaining the theory and computer code is not presented for all topics. The new topics covered range from dynamics to piezo-electricity. However, the main idea, to provide an explanation of the Boundary Element Method (BEM), that is easy for engineers and scientists to follow, is retained. This is achieved by explaining some aspects of the method in an engineering rather than mathematical way. Another new feature of the book is that it deals with the implementation of the method on parallel processing hardware. I. M. Smith, who has been involved in programming the finite element method for decades, illustrates that the BEM is 'embarrassingly parallelisable'. It is shown that the conversion of the BEM programs to run efficiently on parallel processing hardware is not too difficult and the results are very impressive, such as solving a 20 000 element problem during a 'coffee break'.
