Iutam Symposium On Impact Biomechanics From Fundamental Insights To Applications

Substantialfundamental workhas been undertaken inthe different aspects of impact biomechanics over the past three decades. Much of this has been motivated and undertaken bythe automotive industry intheirefforts to improve transport safety. More recently, however, it has become app- ent that themultidisciplinary synergies which are realisedby interactions between engineers, scientists and clinical practitioners will ultimately lead to a greater understanding of the complex interacting phenomena withinthe human bodyafter it has sustained an impact. In turn, this greater depth of knowledge will provide more fundamentalinsights into the analysis, d- gnosis, treatment and prevention ofimpact injuries across a broader sp- trum of accident environments. Thescienti?c focus of this IUTAM symposium istoaddress those t- ics that are centrally important to the biomechanics ofimpact. These can be groupedinto those that are concerned with the different causes of - cidents (e. g., transport, occupational and sports injuries), themechanics - volvedinaccident analysis (e. g., accident investigation, computational m- elling techniques), the different types of resulting traumatic injuries (incl- ing musculoskeletal, organ, spinal and head injuries), methods of asse- ing the extent of injury (e. g., injury assessment, injury criteria, constitutive laws for human tissue), and providing protection during an impact (e. g., injury prevention, energy absorption materials, and safety devices).

Substantial fundamental work has been undertaken in the different aspects of impact biomechanics over the past three decades. Much of this has been motivated and undertaken by the automotive industry in their efforts to improve transport safety. More recently, however, it has become apparent that the multidisciplinary synergies which are realised by interactions between engineers, scientists and clinical practitioners will ultimately lead to a greater understanding of the complex interacting phenomena within the human body after it has sustained an impact. In turn, this greater depth of knowledge will provide more fundamental insights into the analysis, diagnosis, treatment and prevention of impact injuries across a broader spectrum of accident environments. This book contains the edited papers of the IUTAM Symposium on the Biomechanics of Impact, which was held in University College Dublin, Ireland in July 2005. These papers can be grouped into those that are concerned with the different causes of accidents (e.g., transport, occupational and sports injuries), the mechanics involved in accident analysis (e.g., accident investigation, computational modelling techniques), the different types of resulting traumatic injuries (including musculoskeletal, organ, spinal and head injuries), methods of assessing the extent of injury (e.g., injury assessment, injury criteria, constitutive laws for human tissue), and providing protection during an impact (e.g., injury prevention, energy absorption materials, and safety devices). Researchers active in the area of biomechanics will find the book very useful in addressing recent developments in these areas.

This volume contains the proceedings of the IUTAM Symposium on Elastohydrodynamics and Microelastohydrodynamics held in Cardiff from 1-3 September 2004. It contains 31 articles by leading researchers in the field. The symposium focused on theoretical, experimental and computational issues in elastohydrodynamic lubrication (EHL) both in relation to smooth surfaces and in situations where the film is of the same order or thinner than the surface roughness (micro-EHL). The last IUTAM Symposium in this general area of contact of deformable bodies was in 1974. The emphasis in the Symposium was upon fundamental issues such as: solution methods; lubricant rheological models, thermal effects; both low and high elastic modulus situations; human and replacement joints; fluid traction; dynamic effects, asperity lubrication and the failure of lubrication; surface fatigue and thermal distress under EHL conditions. The book will be useful to those active in basic elastohydrodynamics research who wish to gain an up-to-date understanding of the subject from leading experts in the field.

This book synthesizes the results of the seventh in a successful series of workshops that were established by Shanghai Jiao Tong University and Technische Universität Berlin, bringing together researchers from both universities in order to present research results to an international community. Aspects covered here include, among others, Models and specification; Simulation of different properties; Middleware for distributed real-time systems; Signal Analysis; Control methods; Applications in airborne and medical systems.

This book collects peer-reviewed lectures of the IUTAM Symposium on the 100th anniversary of Boundary Layer research. No other reference of this calibre, on this topic, is likely to be published for the next decade. Covers classification, definition and mathematics of boundary layers; instability of boundary layers and transition; boundary layers control; turbulent boundary layers; numerical treatment and boundary layer modelling; special effects in boundary layers.

This volume offers edited papers presented at the IUTAM-Symposium Topological design optimization of structures, machines and materials - status and perspectives, October 2005. The papers cover the application of topological design optimization to fluid-solid interaction problems, acoustics problems, and to problems in biomechanics, as well as to other multiphysics problems. Also in focus are new basic modelling paradigms, covering new geometry modelling such as level-set methods and topological derivatives.

Integrating macroscopic properties with observations at lower levels, this book details advances in multiscale modelling and analysis pertaining to classes of composites which either have a wider range of relevant microstructural scales, such as metals, or do not have a very well-defined microstructure, e.g. cementitious or ceramic composites. The IUTAM symposia proceedings provide a platform for extensive further discussion and research.

Annotation This is the first monograph devoted to the foundation of the theory of composite anisotropic thin-walled beams and to its applications in various problems involving the aeronautical/aerospace, helicopter, naval and mechanical structures. Throughout the theoretical part, an effort was made to provide the treatment of the subject by using the equations of the 3-D elasticity theory. Non-classical effects such as transverse shear, warping constraint, anisotropy of constituent materials yielding the coupling of twist-bending (lateral), bending (transversal)-extension have been included and their implications have been thoroughly analyzed. Thermal effects have been included and in order to be able to circumvent their deleterious effects, functionally graded materials have been considered in their construction. Implications of the application of the tailoring technique and of the active feedback control on free vibration, dynamic response, instability and aeroelasticity of such structures have been amply investigated. Special care was exercised throughout this work to address and validate the adopted solution methodologies and the obtained results against those available in the literature and obtained via numerical or experimental means.
