Preventive Biomechanics

How can we optimize a bedridden patient's mattress? How can we make a passenger seat on a long distance flight or ride more comfortable? What qualities should a runner's shoes have? To objectively address such questions using engineering and scientific methods, adequate virtual human body models for use in computer simulation of loading scenarios are required. The authors have developed a novel method incorporating subject studies, magnetic resonance imaging, 3D-CAD-reconstruction, continuum mechanics, material theory and the finite element method. The focus is laid upon the mechanical in vivo-characterization of human soft tissue, which is indispensable for simulating its mechanical interaction with, for example, medical bedding or automotive and airplane seating systems. Using the examples of arbitrary body support systems, the presented approach provides visual insight into simulated internal mechanical body tissue stress and strain, with the goal of biomechanical optimization of body support systems. This book is intended for engineers, manufacturers and physicians and also provides students with guidance in solving problems related to support system optimization.

Prof. Dr.-Ing. habil. Gerhard Silber, born 1950, obtained his degree in Mechanical Engineering at the Technical University of Applied Sciences Berlin (1975 - 1978) and at the Technical University Berlin (1978 - 1982), where he subsequently received his PhD and habilitated in the field of Continuum Mechanics and Material Theory. From 1989 to 1992 he was employed in the machinery and equipment industry where he was promoted to specialist group leader. In 1992 he was appointed Professor for Engineering Mechanics and Continuum Mechanics at the University of Applied Sciences in Frankfurt/Main. Since 2002 he has been the Managing Director of the Institute for Materials Science (IfM), and since 2005 also Deputy Managing Director of the Center of Biomedical Engineering (Cbme) in Frankfurt/Main. Since 2010 he has been the academic director of the federal state government program "Landes-Offensive zur Entwicklung Wissenschaftlich-ökonomischer Exzellenz" (Loewe) in the state of Hesse (Germany), focussing on Preventive Biomechanics (PräBionik). In 1997 he was awarded the Innovation Award from the sponsoring society of the University of Applied Sciences/Frankfurt. In 2008 he was appointed as a candidate for the German Future Award initiated by the Bmbf and for the Research Award initiated by the state Universities of Applied Sciences.

Dr. rer. med. Christophe Then, born 1971, received his PhD for finite element research in the field of biomechanics of human soft tissue. After several years of employment in the automotive and applied film industry, as a project engineer in the field of finite element analysis, he currently holds the position of research associate in the Department of Diagnostic and Interventional Radiology of the Goethe-University and in the Institute for Materials Science (IfM) of the University of Applied Sciences in Frankfurt/Main.
