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 materials fail in service reviews the latest forensic engineering techniques used in the investigation of failed polymer materials. It gives a series of case studies which illustrate the different types of failure and the forensic engineering techniques used in their investigation.
