Book Description
The results of a study of accident data on side-impact, fixed-object collisions are presented in this report. The Fatal Accident Reporting System (FARS) was used to determine basic characteristics of this type of collision such as seating position of fatally injured occupants, roadway type, surface conditions, and vehicle weights. The National Accident Sampling System (NASS) was used to examine these same characteristics for accidents of all severities. In addition, the effects of breakaway objects, guardrails, and impact conditions on these collisions were examined using the NASS data. Characteristics of side-impact, fixed-object accidents such as location of impact, body region injured, injury sources, deformation measurements, occupant age, and time of day were also investigated using the NASS data. The characteristics of fixed-object, side impacts were then compared to those of vehicle-to-vehicle side impacts.

Book Description
Designed for the experienced practitioner, this new book aims to help reconstruction specialists with problems they may encounter in everyday analysis. The authors demonstrate how to take the physics behind accidents out of the idealized world and into practical situations. Real-world examples are used to illustrate the methods, clarify important concepts, and provide practical applications to those working in the field. Thoroughly revised, this new edition builds on the original exploration of accident analysis, reconstruction, and vehicle design. Enhanced with new material and improved chapters on key topics, an expanded glossary of automotive terms, and a bibliography at the end of the book providing further reading suggestions make this an essential resource reference for engineers involved in litigation, forensic investigation, automotive safety, and crash reconstruction. Police officers, attorneys, and insurance professionals will also find the book to be a definitive resource in reconstructing accident scenes. New Topics: • Event data recorders (EDRs) • Frictional drag coefficients for sliding tires • Railroad grade-crossing collisions • New practical applications of mathematical methods Enhanced Features: • Expanded glossary of automotive terms • Bibliography with further reading suggestions • Improved chapters on tire forces, rollover accidents, crush energy, pedestrian collisions, vehicle dynamic simulation

Book Description
This fully updated edition presents practices and principles applicable for the reconstruction of automobile and commercial truck crashes. Like the First Edition, it starts at the very beginning with fundamental principles, information sources, and data gathering and inspection techniques for accident scenes and vehicles. It goes on to show how to analyze photographs and crash test data. The book presents tire fundamentals and shows how to use them in spreadsheet-based reverse trajectory analysis. Such methods are also applied to reconstructing rollover crashes. Impacts with narrow fixed objects are discussed. Impact mechanics, structural dynamics, and conservation-based reconstruction methods are presented. The book contains a comprehensive treatment of crush energy and how to develop structural stiffness properties from crash test data. Computer simulations are reviewed and discussed. Extensively revised, this edition contains new material on side pole impacts. It has entirely new chapters devoted to low-speed impacts, downloading electronic data from vehicles, deriving structural stiffness in side impacts, and incorporating electronic data into accident reconstructions

Book Description
In this third edition of Vehicle Accident Analysis & Reconstruction Methods, Raymond M. Brach and R. Matthew Brach have expanded and updated their essential work for professionals in the field of accident reconstruction. Most accidents can be reconstructed effectively using of calculations and investigative and experimental data: the authors present the latest scientific, engineering, and mathematical reconstruction methods, providing a firm scientific foundation for practitioners. Accidents that cannot be reconstructed using the methods in this book are rare. In recent decades, the field of crash reconstruction has been transformed through the use of technology. The advent of event data records (EDRs) on vehicles signaled the era of modern crash reconstruction, which utilizes the same physical evidence that was previously available as well as electronic data that are measured/captured before, during, and after the collision. There is increased demand for more professional and accurate reconstruction as more crash data is available from vehicle sensors. The third edition of this essential work includes a new chapter on the use of EDRs as well as examples using EDR data in accident reconstruction. Early chapters feature foundational material that is necessary for the understanding of vehicle collisions and vehicle motion; later chapters present applications of the methods and include example reconstructions. As a result, Vehicle Accident Analysis & Reconstruction Methods remains the definitive resource in accident reconstruction.

Book Description
Vehicle Collision Dynamics provides a unified framework and timely collection of up-to-date results on front crash, side crash and car to car crashes. The book is ideal as a reference, with an approach that's simple, clear, and easy to comprehend. As the mathematical and software-based modelling and analysis of vehicle crash scenarios have not been systematically investigated, this is an ideal source for further study. Numerous academic and industry studies have analyzed vehicle safety during physical crash scenarios, thus material responses during crashes serve as one of the most important performance indices for mechanical design problems. In addition to mathematical methodologies, this book provides thorough coverage of computer simulations, software-based modeling, and an analysis of methods capable of providing more flexibility. Unifies existing and emerging concepts concerning vehicle crash dynamics Provides a series of latest results in mathematical-based modeling from front and oblique perspectives Contains almost everything needed to capture the essence of model development and analysis for vehicle crash Includes both numerical and simulation results given in each chapter Presents a comprehensive, up-to-date reference that encourages further study
