Informationen zum Autor Jean-François SIGRISTDCNS Research, France Klappentext Fluid-Structure Interaction: An Introduction to Finite Element Coupling fulfils the need for an introductory approach to the general concepts of Finite and Boundary Element Methods (FEM and BEM) for FSI (fluid-structure interaction), from the mathematical formulation to the physical interpretation of numerical simulations. Composed of six chapters, the book progresses logically from formulations and applications involving structure and fluid dynamics, fluid and structure interactions and opens to reduced-order modelling for vibro-acoustic coupling. The author describes simple yet fundamental illustrative examples in detail, using analytical and/or semi-analytical formulations, designed to both illustrate each numerical method and to highlight a physical aspect of FSI. All proposed examples are simple enough to be computed by the reader using standard computational tools such as MATLAB(r), making the book a unique tool for self-learning and understanding the basics of the techniques for FSI. Test cases for FEM/FEM or FEM/BEM coupling techniques also render the book valuable for code verification and validation purposes.Key Features:* Easy-to-read introduction to mathematical/numerical modelling of FSI* Provides a first approach on 'classical' numerical techniques and is suited to undergraduate students as well as practicing engineers* Illustrates the physics of structural-acoustics coupling with various examples of academic and industrial interest* Is a good companion for the practice of Finite and Boundary Element Methods with any engineering simulation software* Accompanied by a website hosting MATLAB(r) codes and Powerpoint slidesBased on the author's experience in developing numerical codes for industrial applications and teaching FSI to both practicing engineers and within academia, Fluid-Structure Interaction: An Introduction to Finite Element Coupling is a comprehensive and self-contained guide for both students and practitioners of mechanical engineering. Zusammenfassung Fluid-Structure Interaction: An Introduction to Finite Element Coupling fulfils the need for an introductive approach to the general concepts of Finite and Boundary Element Methods for FSI, from the mathematical formulation to the physical interpretation of numerical simulations.
