Book Description
A three-dimensional finite element model of the human head is presented. The model has been validated against two sets of experimental results. To assess injury likelihood of the head subjected to impact loading, the structural intensity (SI) methodology is introduced in accordance with the prevailing practice in experimental biomechanics. SI is a vector quantity indicating the direction and magnitude of power flow inside a dynamically loaded structure. In this paper, the SI field inside the head model is computed for three cases, namely frontal, rear and side impacts. The results for the three cases have revealed that there exist power flow paths. The skull is, in general, a good energy flow channel. The study has also revealed the high possibility of spinal cord injury due to wave motion inside the head.

Book Description
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.

Book Description
This book covers many aspects of Injury and Skeletal Biomechanics. As the title represents, the aspects of force, motion, kinetics, kinematics, deformation, stress and strain are examined in a range of topics such as human muscles and skeleton, gait, injury and risk assessment under given situations. Topics range from image processing to articular cartilage biomechanical behavior, gait behavior under different scenarios, and training, to musculoskeletal and injury biomechanics modeling and risk assessment to motion preservation. This book, together with "Human Musculoskeletal Biomechanics", is available for free download to students and instructors who may find it suitable to develop new graduate level courses and undergraduate teaching in biomechanics.

Book Description
The 26th Southern Biomedical Engineering Conference was hosted by the Fischell Department of Bioengineering and the A. James Clark School of Engineering from April 30 – May 2 2010.. The conference program consisted of 168 oral presentations and 21 poster presentations with approximately 250 registered participants of which about half were students. The sessions were designed along topical lines with student papers mixed in randomly with more senior investigators. There was a Student Competition resulting in several Best Paper and Honorable Mention awards. There were 32 technical sessions occurring in 6-7 parallel sessions. This Proceedings is a subset of the papers submitted to the conference. It includes 147 papers organized in topical areas. Many thanks go out to the paper reviewers who significantly improved the clarity of the submitted papers.

Book Description
Military Injury Biomechanics: The Cause and Prevention of Impact Injuries is a reference manual where information and data from a large number of sources, focussing on injuries related to military events, has been critically reviewed and discussed. The book covers the cause and prevention of impact injuries to all the major body regions, while topics such as the historical background of military impact biomechanics, the history and use of anthropomorphic test devices for military applications and the medical management of injuries are also discussed. An international team of experts have been brought together to examine and review the topics. The book is intended for researchers, postgraduate students and others working or studying defence and impact injuries.

Book Description
In the post-Daubert era, forensic science disciplines are increasingly informed by robust, statistically-sound experimental research. The educational value of the well-documented case study, however, remains as important as ever. Emphasizing known contextual information, this volume serves as a case-driven guide to skeletal trauma analysis through the unique perspective of each chapter's authors. Both forensic anthropologists and pathologists contribute skeletal trauma cases covering a range of topics including child abuse, blunt force trauma, descents from height, plane crashes, sharp force trauma and dismemberment, gunshot wounds, blast trauma, and burned body interpretation. Several chapters also include a discussion of potentially confounding taphonomic influences such as animal scavenging, water immersion, burning, and extended postmortem intervals. Detailed descriptions with multiple supporting images allow the practitioner's skeletal trauma interpretation to be compared to the "answer" as it pertains to the known circumstances surrounding the traumatic events of each case.

Book Description
Damage to the central nervous system resulting from pathological mechanical loading can occur as a result of trauma or disease. Such injuries lead to significant disability and mortality. The peripheral nervous system, while also subject to injury from trauma and disease, also transduces physiological loading to give rise to sensation, and mechanotransduction is also thought to play a role in neural development and growth. This book gives a complete and quantitative description of the fundamental mechanical properties of neural tissues, and their responses to both physiological and pathological loading. This book reviews the methods used to characterize the nonlinear viscoelastic properties of central and peripheral neural tissues, and the mathematical and sophisticated computational models used to describe this behaviour. Mechanisms and models of neural injury from both trauma and disease are reviewed from the molecular to macroscopic scale. The book provides a comprehensive picture of the mechanical and biological response of neural tissues to the full spectrum of mechanical loading to which they are exposed. This book provides a comprehensive reference for professionals involved in pre prevention of injury to the nervous system, whether this arises from trauma or disease.
