He has initiated European working groups on composites fractography, conducted numerous failure investigations and has led involvement in high profile component failures (e.g. Formula One crashes) and as an expert witness in litigation cases. He has delivered training courses on fractography to industry and university students. He is recognised as one of the world experts on failure analysis of composites. Dr Silvestre Pinho works in the Department of Aeronautics at Imperial College London, UK. He is widely renowned for his expertise on the failure mechanics of composite materials. Klappentext The book focuses on three main types of failure: impact damage! delamination! and fatigue. There are sections aimed specifically at the aerospace! automotive! civil engineering! and marine industries in which composite materials are most heavily used. Zusammenfassung This book focuses on three main types of failure: impact damage! delamination and fatigue. Chapters in part one describe the causes of failure such as impact damage! manufacturing defects and fire.
