Durability Of Composite Systems

Durability of Composite Systems meets the challenge of defining these precepts and requirements, from first principles, to applications in a diverse selection of technical fields selected to form a corpus of concepts and methodologies that define the field of durability in composite material systems as a modern discipline. That discipline includes not only the classical rigor of mechanics, physics and chemistry, but also the critical elements of thermodynamics, data analytics, and statistical uncertainty quantification as well as other requirements of the modern subject. This book provides a comprehensive summary of the field, suited to both reference and instructional use. It will be essential reading for academic and industrial researchers, materials scientists and engineers and all those working in the design, analysis and manufacture of composite material systems. Makes essential direct and detailed connections to modern concepts and methodologies, such as machine learning, systems controls, sustainable and resilient systems, and additive manufacturing Provides a careful balance between theory and practice so that presentations of details of methodology and philosophy are always driven by a context of applications and examples Condenses selected information regarding the durability of composite materials in a wide spectrum of applications in the automotive, wind energy, civil engineering, medical devices, electrical systems, aerospace and nuclear fields

The papers from these proceedings address experimental and analytical methods for the characterization and analysis of modern composite and adhesive systems. They have been produced to provide understanding that can be used to design safe, reliable engineering components.

Composite material systems are the basis for much of the natural world around us and are rapidly becoming the basis for many modern engineering components. A controlling feature for the general use of such systems is their damage tolerance, durability and reliability. The present book is a comprehensive cross section of the state of the art in the field of the durability of polymer-based, composite, and adhesive systems. As such, it is of special value to researchers concerned with the frontier of the field, to students concerned with the substance of the subject, and to the applied community concerned with the finding methodologies that make it possible to design safe and durable engineering components using material systems.

This proceedings covers the general problem related to the damage initiation and development, the failure criteria and the specific aspects related to fatigue, creep behaviour, moisture diffusion and the problem of the joining systems.

This set of conference papers on composite materials systems covers such topics as: general aspects and methods; fatigue behaviour; damage; accelerated testing; influence of water on the properties; and specific systems and structures.

Durability analysis can be defined as the prediction methodology of safe residual behaviour after a given life time under a complex mechanical loading history in combination with a program of environmental variations. This was, and is a central problem for the reliability of structural components whatever are the basic material systems. With composite systems, combination of different materials in interaction, an integrated material structure design becomes possible. If one of the phases is a polymer, the composite system has time dependent properties and as consequence durability analysis has to be performed taking into account the internal time factor in combination with strong influences from temperature changes and moisture diffusion. Insurance companies need information on durability and reliability in order to cover the risks, and in the event of failure lawyers have to arrive at an agreement om the responsibilites of the different actors involved in the constructiion. This book is an overview of the state of the different aspects of safe structural integrity for a given lifetime of composite structures, with special emphasis on polymer matrix composites. It is of interest for scientists and engineers involved in composites and for designers of composite structural components.

Advanced, high-performance composite materials are really material systems. The constituent materials interact in such a way that their collective response is more than the linear sum of the response of the constituents. This simple reality provides the technical community with a remarkable opportunity to create composite material systems which are uniquely suited to perform specific engineering tasks. At the same time, this systems aspect of composite materials is a very great challenge to the research community. In introduces complexity, nonlinearity, and scaling problems (to name a few) which require the development of new representations of material behavior, from the standpoint of mechanics, chemistry, and physics.
