Given the infinite number of applications of polymeric materials in everyday life, especially applications where a failure in service may lead to economic loss, injury or death, the ability to determine the cause of failure using forensic engineering techniques is essential. Forensic polymer engineering: Why polymer products fail in service reviews the latest forensic engineering techniques used in the investigation of failed polymer materials. It presents a series of case studies which illustrate the different types of failure and the forensic engineering techniques used in their investigation. The first chapters give an introduction to forensic polymer engineering and an overview of the examination and analysis of failed polymer components. Further chapters give detailed case studies of failure and forensic investigation of polymeric medical devices, polymer storage tanks, small polymeric containers, polymer pipes and fittings, polymeric seals, polymeric tools and ladders, polymer components in transport applications and polymer consumer products. A final concluding chapter provides information on causes of product failure and discusses poor manufacturing methods, poor design, poor choice of materials and failure due to insufficient account being taken of environmental factors. With its distinguished authors, Forensic polymer engineering: Why polymer products fail in service is a standard reference for forensic experts practicing in all engineering fields that involve polymeric materials, as well as design and construction professionals, product manufacturers and insurance professionals. Reviews the latest forensic engineering techniques used in the investigation of failed polymer components Detailed case studies illustrate different types of failure in polymer components, fittings and medical devices Examines the role of manufacturing in product failure with an overview of faults recognised in methods, design and material selection
This book approaches the analysis of forensic contact traces from a polymer science perspective. The development of characterization methods of new or unusual traces and the improvement of existing protocols is described. The book starts with a general introduction to polymers and the issues related to transfer, persistence and recovery of polymeric traces. The chapters present a distinctive feature of polymers, discussing how it can be measured, what the practical difficulties which can be encountered in the analysis, and how useful that information is for comparison or identification purposes. Practical tips for the realization of the forensic analyses are included.
Forensic Engineering: The Art and Craft of a Failure Detective synthesizes the current academic knowledge, with advances in process and techniques developed in the last several years, to bring forensic materials and engineering analysis into the 21st century. The techniques covered in the book are applied to the myriad types of cases the forensic engineer and investigator may face, serving as a working manual for practitioners. Analytical techniques and practical, applied engineering principles are illustrated in such cases as patent and intellectual property disputes, building and product failures, faulty design, air and rail disasters, automobile recalls, and civil and criminal cases. Both private and criminal cases are covered as well as the legal obligation, requirements, and responsibilities under the law, particularly in cases of serious injury or even death. Forensic Engineering will appeal to professionals working in failure analysis, loss adjustment, occupational health and safety as well as professionals working in a legal capacity in cases of produce failure and liability—including criminal cases, fraud investigation, and private consultants in engineering and forensic engineering.
Most books on forensic engineering focus on civil engineering failures rather than consumer or general mechanical products. Unique both in scope and style, this treatment is built upon case studies of real accidents, broadly focused on consumer products, and dedicated to problem solving through scientific principles. Each well-illustrated case study includes legal background, reports the case results, and highlights the lessons learned from the case. New materials and applications appear constantly, and with them, new failure modes. This book provides an outstanding opportunity to gain virtual experience through up-to-date facts and feedback from forensic engineering practitioners.
Given the widespread use of polymers in medical devices, the durability and reliability of this material in use is an area of critical importance. Durability and reliability of medical polymers reviews the performance of both bioresorbable and non-bioresorbable medical polymers. Part one provides a review of the types and properties of bioresorbable medical polymers. The effect of molecular structure on properties is discussed, along with the processing of bioresorbable and other polymers for medical applications. Transport phenomena and the degradation of bioresorbable medical polymers are reviewed, before an exploration of synthetic bioresorbable polymers and their use in orthopaedic tissue regeneration. Part two goes on to explore the durability and reliability of non-bioresorbable medical polymers, and wear processes in polymer implants and ageing processes of biomedical polymers in the body are discussed in depth, before an investigation into manufacturing defects and the failure of synthetic polymeric medical devices. With its distinguished editors and international team of expert contributors, Durability and reliability of medical polymers is an essential tool for all materials scientists, researchers and engineers involved in the design, development and application of medical polymers, whilst also providing a helpful overview of the subject for biologists, chemist and clinicians.

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
Forensic Microbiology focuses on newly emerging areas of microbiology relevant to medicolegal and criminal investigations: postmortem changes, establishing cause of death, estimating postmortem interval, and trace evidence analysis. Recent developments in sequencing technology allow researchers, and potentially practitioners, to examine microbial communities at unprecedented resolution and in multidisciplinary contexts. This detailed study of microbes facilitates the development of new forensic tools that use the structure and function of microbial communities as physical evidence. Chapters cover: Experiment design Data analysis Sample preservation The influence of microbes on results from autopsy, toxicology, and histology Decomposition ecology Trace evidence This diverse, rapidly evolving field of study has the potential to provide high quality microbial evidence which can be replicated across laboratories, providing spatial and temporal evidence which could be crucial in a broad range of investigative contexts. This book is intended as a resource for students, microbiologists, investigators, pathologists, and other forensic science professionals.
