Most existing computational human body models were developed using the finite element method (FEM). Although FEM has made great progress in the structure analysis area, there are certain problems that are difficult for FEM. One of these difficulties is the fluid and structure interaction (FSI) analysis.

This book starts by introducing the fundamental concepts of mathematical continuum mechanics for fluids and solids and their coupling. Special attention is given to the derivation of variational formulations for the subproblems describing fluid- and solid-mechanics as well as the coupled fluid-structure interaction problem. Two monolithic formulations for fluid-structure interactions are described in detail: the well-established ALE formulation and the modern Fully Eulerian formulation, which can effectively deal with problems featuring large deformation and contact. Further, the book provides details on state-of-the-art discretization schemes for fluid- and solid-mechanics and considers the special needs of coupled problems with interface-tracking and interface-capturing techniques. Lastly, advanced topics like goal-oriented error estimation, multigrid solution and gradient-based optimization schemes are discussed in the context of fluid-structure interaction problems.

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. Based on the author’s experience in developing numerical codes for industrial applications in shipbuilding and in teaching FSI to both practicing engineers and within academia, it provides a comprehensive and self–contained guide that is geared toward both students and practitioners of mechanical engineering. Composed of six chapters, Fluid–Structure Interaction: An Introduction to Finite Element Coupling 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 formulation & designed both to illustrate each numerical method and also 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, making the book a unique tool for self–learning and understanding the basics of the techniques for FSI, or can serve as verification and validation test cases of industrial FEM/BEM codes rendering the book valuable for code verification and validation purposes.

To facilitate the evaluation and design of structures subjected to fluid loading, a study of fluid-structure interaction (FSI) using the particle finite element method (PFEM) is presented to approximate the responses and sensitivities of structures which interact with fluid. A wide range of structural types are permissible by making no assumptions of the configurations, materials or any properties of the structures. On the other hand, the Newtonian flows are assumed, which are sufficient for the fluid that interacts with structures, such as bridges, coastal buildings and off-shore structures. The particle finite element method is used here as the primary tool for numerical computation with two advantages. First, both fluid and structural domains are described with Lagrangian formulation in PFEM, which conform to the traditional formulation for structural mechanics. Therefore, the interaction and coupling of both domains can be naturally described at level of differential equations. Second, the PFEM is a particle based method, where particles are moved by their own mass and interaction between connected particles. This is convenient to free surface problems, which is common in most of our applications. In order to accommodate arbitrary structures in PFEM, the fractional step method (FSM) used in the original PFEM is modified with better accuracy and convergence rate. An unified FSM is also proposed for fluid with high viscosity and fluid elements with consistent mass matrix. The MINI element is used in this study as replacement of the stabilized linear element to eliminate the additional unknowns in the original PFEM. As a prerequisite to the reliability based structural design, the sensitivity analysis of PFEM is studied using the direct differentiation method (DDM). The large displacement of the fluid domain is considered in forming the sen- sitivity equations of FSI by introducing the additional geometric sensitivity. The structural finite element software, OpenSees, is chosen as the platform for implemen- tation. It is extended by adding new modules at high and low levels of the software framework. Numerical results computed by OpenSees using PFEM are compared to analytical solutions, experimental data and results from other numerical methods which are shown from Chapter 2 to 5.

The RKPM method also plays an important role in the Immersed Finite Element Method (IFEM), a new approach in solving complex fluid-structure interaction problems. The interpolations of the variables between the fluid and the solid domains are calculated via the RKPM shape functions. This RKPM delta functions can handle nonuniform grids for the fluid domain, which allows the definition of arbitrary geometry shapes and boundary conditions. It broadens the flexibilities in treating typical fluid-structure interactions with detailed and realistic stress analysis. Particulate flows of rigid and deformable spheres are illustrated as examples. Future research and potential possible applications in the field of bio-engineering mechanics are stated.

This book is dedicated to the general study of fluid structure interaction with consideration of uncertainties. The fluid-structure interaction is the study of the behavior of a solid in contact with a fluid, the response can be strongly affected by the action of the fluid. These phenomena are common and are sometimes the cause of the operation of certain systems, or otherwise manifest malfunction. The vibrations affect the integrity of structures and must be predicted to prevent accelerated wear of the system by material fatigue or even its destruction when the vibrations exceed a certain threshold.

This book treats the derivation and implementation of a unified particle finite element formulation for the solution of fluid and solid mechanics, Fluid-Structure Interaction (FSI) and coupled thermal problems. FSI problems are involved in many engineering branches, from aeronautics to civil and biomedical engineering. The numerical method proposed in this book has been designed to deal with a large part of these. In particular, it is capable of simulating accurately free-surface fluids interacting with structures that may undergo large displacements, suffer from thermo-plastic deformations and even melt. The method accuracy has been successfully verified in several numerical examples. The thesis also contains the application of the proposed numerical strategy for the simulation of a real industrial problem. This thesis, defended at the Universitat Politecnica de Catalunya in 2015, was selected (ex aequo) as the best PhD thesis in numerical methods in Spain for the year 2015 by the Spanish Society of Numerical Methods in Engineering (SEMNI).

The interaction of a fluid with a solid body is a widespread phenomenon in nature, occurring at different scales and different applied disciplines. Interestingly enough, even though the mathematical theory of the motion of bodies in a liquid is one of the oldest and most classical problems in fluid mechanics, mathematicians have, only very recently, become interested in a systematic study of the basic problems related to fluid-structure interaction, from both analytical and numerical viewpoints.Fundamental Trends in Fluid-Structure Interaction is a unique collection of important papers written by world-renowned experts aimed at furnishing the highest level of development in several significant areas of fluid-structure interactions. The contributions cover several aspects of this discipline, from mathematical analysis, numerical simulation and modeling viewpoints, including motion of rigid and elastic bodies in a viscous liquid, particulate flow and hemodynamic.
