This book is not an advanced engineering text. Rather, it is a practical presentation with traffic accident reconstruction principles presented in a simple, understandable manner so that the reader will easily retain these important concepts. The engineering principles involved are introduced at the elementary level, and in many cases equations used in freshman physics are derived. The authors believe that the derivations are presented in the simplest manner possible so that the reader will retain this material. The book is the result of an effort to compile over a period of years useful forensic engineering data, information, and analytical techniques over and above those taught to non-engineers. Many of the mathematical treatments are original. In general, the book reflects the authors' combined over forty years experience of forensic investigations involving thousands of cases. It offers something for everyone interested in forensic engineering. In the new second edition, Chapters 3 to 5 have been substantially modified, and the remainder of the text has been edited to bring its various parts up to date. The experienced investigator will find a wealth of new ideas and relationships to fill in gaps in his knowledge and reinforce his analytical approaches. Those starting new in this work will have an advantage on their competition after studying this material. For the non-technical reader, most of the book is eminently readable. To an investigator, attorney, or insurance adjuster with only a nodding acquaintance with freshman physics, the book should be totally comprehensible.

Bicycle Accident Reconstruction for the Forensic Engineer describes the methodology for reconstructing bicycle and pedestrian accidents. Of particular interest is analysis of light, signation and conspicuity on the reconstruction of all types of accidents.

Over the past 25 years, Harold and Darren Franck have investigated hundreds of accidents involving vehicles of almost every shape, size, and type imaginable. In Mathematical Methods for Accident Reconstruction: A Forensic Engineering Perspective, these seasoned experts demonstrate the application of mathematics to modeling accident reconstructions

Accident reconstruction utilizes principles of physics and empirical data to analyze the physical, electronic, video, audio, and testimonial evidence from a crash, to determine how and why the crash occurred, how the crash could have been avoided, or to determine whose description of the crash is most accurate. This process draws together aspects of mathematics, physics, engineering, materials science, human factors, and psychology, and combines analytical models with empirical test data. Different types of crashes produce different types of evidence and call for different analysis methods. Still, the basic philosophical approach of the reconstructionist is the same from crash type to crash type, as are the physical principles that are brought to bear on the analysis. This book covers a basic approach to accident reconstruction, including the underlying physical principles that are used, then details how this approach and the principles are applied when reconstructing motorcycle crashes. This second edition of Motorcycle Accident Reconstruction presents a thorough, systematic, and scientific overview of the available methods for reconstructing motorcycle crashes. This new edition contains: Additional theoretical models, examples, case studies, and test data. An updated bibliography incorporating the newest studies in the field. Expanded coverage of the braking capabilities of motorcyclists. Updated, refined, and expanded discussion of the decelerations of motorcycles sliding on the ground. A thoroughly rewritten and expanded discussion of motorcycle impacts with passenger vehicles. Updated coefficients of restitution for collisions between motorcycles and cars. A new and expanded discussion of using passenger car EDR data in motorcycle accident reconstruction. A new section covering recently published research on post-collision frozen speedometer readings on motorcycles. A new section on motorcycle interactions with potholes, roadway deterioration, and debris and expanded coverage of motorcycle falls. This second edition of Motorcycle Accident Reconstruction is a must-have title for accident reconstructionists, forensic engineers, and all interested in understanding why and how motorcycle crashes occur.

Accident investigation/reconstruction is more than just a job or even a profession; it is more art than science and requires a dedication greater than a commitment of time. It takes constant reading, study, and analysis of accident information and case reconstructions to keep improving your performance, both in the field and in the courtroom.

Forensic Engineering, the latest edition in the Advanced Forensic Science series that grew out of recommendations from the 2009 NAS Report: Strengthening Forensic Science: A Path Forward, serves as a graduate level text for those studying and teaching digital forensic engineering, as well as an excellent reference for a forensic scientist's library or for their use in casework. Coverage includes investigations, transportation investigations, fire investigations, other methods and professional issues. Edited by a world-renowned leading forensic expert, this series is a long overdue solution for the forensic science community. - Provides basic principles of forensic science and an overview of forensic engineering - Contains sections on investigations, transportation investigations, fire investigations and other methods - Includes a section on professional issues, such as: from crime scene to court, forensic laboratory reports and health and safety - Incorporates effective pedagogy, key terms, review questions, discussion questions and additional reading suggestions

Forensic engineers often specialize in a particular area such as structures, fires, or accident reconstruction. However, the nature of the work often requires broad knowledge in the interrelated areas of physics, chemistry, biomechanics, and engineering. Covering cases as varied as assessment of workplace accidents to the investigation of Halliburt

Accident analysis is not like a classroom problem where the equations are selected and solved, and the matter is considered closed. In this line of forensics, engineering skill must be combined with skillful practice for the successful presentation of evidence to a jury. In this book, the author demonstrates the application of engineering skills, methods, and judgment for analyzing vehicular accidents. A definition of vehicular accident reconstruction and its role in the legal system is provided. General accident statistics are cited, and some general strategies for accident reconstruction are given, along with many examples and case studies. The author includes novel and unusual treatment of the momentum method and coefficient of restitution (which is not yet widespread in accident analysis) and shows how to select the best methods of analysis in a given accident reconstruction.

In this work the development of a new geometrically detailed finite element head model is presented. Special attention is given to sulci and gyri modelling, making this model more geometrically accurate than others currently available. The model was validated against experimental data from impact tests on cadavers, specifically intracranial pressure and brain motion. Its potential is shown in an accident reconstruction case with injury evaluation by effectively combining multibody kinematics and finite element methodology.
