The growing use of polymer composites is leading to increasing demand for fractographic expertise. Fractography is the study of fracture surface morphologies and it gives an insight into damage and failure mechanisms, underpinning the development of physically-based failure criteria. In composites research it provides a crucial link between predictive models and experimental observations. Finally, it is vital for post-mortem analysis of failed or crashed polymer composite components, the findings of which can be used to optimise future designs. Failure analysis and fractography of polymer composites covers the following topics: methodology and tools for failure analysis; fibre-dominated failures; delamination-dominated failures; fatigue failures; the influence of fibre architecture on failure; types of defect and damage; case studies of failures due to overload and design deficiencies; case studies of failures due to material and manufacturing defects; and case studies of failures due to in-service factors. With its distinguished author, Failure analysis and fractography of polymer composites is a standard reference text for researchers working on damage and failure mechanisms in composites, engineers characterising manufacturing and in-service defects in composite structures, and investigators undertaking post-mortem failure analysis of components. The book is aimed at both academic and industrial users, specifically final year and postgraduate engineering and materials students researching composites and industry designers and engineers in aerospace, civil, marine, power and transport applications. * Examines the study of fracture surface morphologies in uderstanding composite structural behaviour* Discusses composites research and post-modern analysis of failed or crashed polymer composite components* Provides an overview of damage mechanisms, types of defect and failure criteria

Better Understand the Relationship between Powertrain System Design and Its Control Integration.While powertrain system design and its control integration are traditionally divided into two different functional groups, a growing trend introduces the integration of more electronics (sensors, actuators, and controls) into the powertrain system. This has impacted the dynamics of the system, changing the traditional mechanical powertrain into a mechatronic powertrain, and creating new opportunities for improved efficiency. Design and Control of Automotive Propulsion Systems focuses on the ICE-based automotive powertrain system (while presenting the alternative powertrain systems where appropriate). Factoring in the multidisciplinary nature of the automotive propulsion system, this text does two thingsadopts a holistic approach to the subject, especially focusing on the relationship between propulsion system design and its dynamics and electronic control, and covers all major propulsion system components, from internal combustion engines to transmissions and hybrid powertrains.The book introduces the design, modeling, and control of the current automotive propulsion system, and addresses all three major subsystems: system level optimization over engines, transmissions, and hybrids (necessary for improving propulsion system efficiency and performance). It provides examples for developing control-oriented models for the engine, transmission, and hybrid. It presents the design principles for the powertrain and its key subsystems. It also includes tools for developing control systems and examples on integrating sensors, actuators, and electronic control to improve powertrain efficiency and performance. In addition, it presents analytical and experimental methods, explores recent achievements, and discusses future trends.Comprised of five chapters containing the fundamentals as well as new research, this text:- Examines the design, modeling, and control of the internal combustion engine and its key subsystems: the valve actuation system, the fuel system, and the ignition system- Expounds on the operating principles of the transmission system, the design of the clutch actuation system, and transmission dynamics and control- Explores the hybrid powertrain, including the hybrid architecture analysis, the hybrid powertrain model, and the energy management strategies- Explains the electronic control unit and its functionalitiesthe software-in-the-loop and hardware-in-the-loop techniques for developing and validating control systemsDesign and Control of Automotive Propulsion Systems provides the background of the automotive propulsion system, highlights its challenges and opportunities, and shows the detailed procedures for calculating vehicle power demand and the associated powertrain operating conditions.

Mechanical vibration is normally an undesired condition which can cause problems such as discomfort, noise, fatigue, etc.Shock is a particular type of vibration of transient nature containing high levels of energy in a very short period of time It is vital for engineers to understand and apply vibration control methods, either by introducing structural modifications, reducing the source of vibration, or interposing an isolator between receiver and source. The easiest mathematical representation of these isolators is a passive combination of a spring and a damping of fixed properties.There are some isolators where the properties can change depending upon the vibration source called semi active, or adaptive vibration isolators.This book explores the application of a novel stiffness switching strategy to achieve an improved shock isolator. This is a two stage strategy controlling the vibration response during the shock and the later residual vibration.The book presents a review of the state of the art in shock isolation, theoretical models for switching stiffness and experimental validation.

Presenting proven methods, practical guidelines, and real-world flight-test results for a wide range of state-of-the-art flight vehicles, Aircraft and Rotorcraft System Identification, Second Edition addresses the entire process of aircraft and rotorcraft system identification from instrumentation and flight testing to model determination, validation, and application of the results.
