Book Description :

Fatigue Life Prediction of Composites and Composite Structures, Second Edition, is a comprehensive review of fatigue damage and fatigue life modeling and prediction methodologies for composites and their use in practice. In this new edition, existing chapters are fully updated, while new chapters are introduced to cover the most recent developments in the field. The use of composites is growing in structural applications in many industries, including aerospace, marine, wind turbine and civil engineering. However, there are uncertainties about their long-term performance, including performance issues relating to cyclic fatigue loading that hinder the adoption of a commonly accepted credible fatigue design methodology for the life prediction of composite engineering structures. With its distinguished editor and international team of contributors, this book is a standard reference for industry professionals and researchers alike. Examines past, present and future trends associated with the fatigue life prediction of composite materials and structures Assesses novel computational methods for fatigue life modeling and prediction of composite materials under constant amplitude loading Covers a wide range of techniques for predicting fatigue, including their theoretical background and practical applications Addresses new topics and covers contemporary research developments in the field

Book Description :

Fiber composites, like metals, exhibit a form of degradation in service described as fatigue. Engineers must understand composite fatigue because it is a causative agent of design and structural failures. Engineers need to increase their knowledge of the mechanisms which result in degradation in order to predict the life of a composite under specified conditions and produce composites with greater durability. This book provides an extensive account of contemporary research on fatigue from a selection of internationally recognized researchers. Part one introduces the concept, delivering a historical review of the fatigue behavior of fiber-reinforced plastics and illustrating fatigue test methods and fatigue under multiaxial stress systems. The second part reviews current research on micromechanical aspects, emphasizing long-term behavior, interface performance, delamination, and damage accumulation. The next two sections cover the analysis and testing of fatigue behavior and detail physical, micromechanical, computational, statistical, and life-prediction models for constant and variable stress. The final parts offer an overview of the wide range of composite fatigue-related problems experienced by engineers in aerospace, marine, and structural engineering.

Book Description :

It is commonly accepted that the majority of engineering failures happen due to fatigue or fracture phenomena. Adhesive bonding is a prevailing joining technique, widely used for critical connections in composite structures. However, the lack of knowledge regarding fatigue and fracture behaviour, and the shortage of tools for credible fatigue design, hinders the potential benefits of adhesively bonded joints. The demand for reliable and safe structures necessitates deep knowledge in this area in order to avoid catastrophic structural failures. This book reviews recent research in the field of fatigue and fracture of adhesively-bonded composite joints. The first part of the book discusses the experimental investigation of the reliability of adhesively-bonded composite joints, current research on understanding damage mechanisms, fatigue and fracture, durability and ageing as well as implications for design. The second part of the book covers the modelling of bond performance and failure mechanisms in different loading conditions. A detailed reference work for researchers in aerospace and engineering Expert coverage of different adhesively bonded composite joint structures An overview of joint failure

Book Description :

Fatigue has long been recognized as a mechanism that can provoke catastrophic material failure in structural applications and researchers are now turning to the development of prediction tools in order to reduce the cost of determining design criteria for any new material. Fatigue of Fiber-reinforced Composites explains these highly scientific subjects in a simple yet thorough way. Fatigue behavior of fiber-reinforced composite materials and structural components is described through the presentation of numerous experimental results. Many examples help the reader to visualize the failure modes of laminated composite materials and structural adhesively bonded joints. Theoretical models, based on these experimental data, are demonstrated and their capacity for fatigue life modeling and prediction is thoroughly assessed. Fatigue of Fiber-reinforced Composites gives the reader the opportunity to learn about methods for modeling the fatigue behavior of fiber-reinforced composites, about statistical analysis of experimental data, and about theories for life prediction under loading patterns that produce multiaxial fatigue stress states. The authors combine these theories to establish a complete design process that is able to predict fatigue life of fiber-reinforced composites under multiaxial, variable amplitude stress states. A classic design methodology is presented for demonstration and theoretical predictions are compared to experimental data from typical material systems used in the wind turbine rotor blade industry. Fatigue of Fiber-reinforced Composites also presents novel computational methods for modeling fatigue behavior of composite materials, such as artificial neural networks and genetic programming, as a promising alternative to the conventional methods. It is an ideal source of information for researchers and graduate students in mechanical engineering, civil engineering and materials science.

Book Description :

The durability and damage tolerant aspects of composite material structural design, are by far the nost complex issues of this technology, and from an analytical point of view, the least understood. No single widely recognized procedure exists for verification of the fatigue/damage tolerant integrity of composite structure. Civil certification programs to date, have in part, consisted of designing to a set of reduced composite strain levels, with substantiation provided through extensive component, subcomponent and coupon testing. The FAA in 1978, with issuance of Advisory Circular AC 25.571-1, "Damage-Tolerance and Fatigue Evaluation of Structures," recommended that future civil safety-of-flight structure be designed damage-tolerant, unless such design entails complications that an effective damage-tolerant structure could not be achieved within the limitations of geometry, inspectability, or good design practice. Advisory Circular AC 20-107, "Composite Aircraft Structure," also issued in 1978, incorporates the concepts set forth in AC 25.571-1. Future civil composite structural designs will therefore most likely be damage tolerant. As fuel considerations continue to be a major design parameter, further reductions in aircraft structural weight will nost likely be achieved through improved composite material damage tolerant design techniques, (e.g., introduction of damage growth stoppers such as stitching, softening strips, etc.) and extensive use of adhesive bonding. The increase in cperating strain levels, however, must be accompanied by the development of substantiated analytical methodologies, capable of reliably predicting composite material's fatigue/damage tolerance response.

Book Description :

Low cycle fatigue (LCF) of laminate composite structures used in Army applications is assessed to identify the key physical phenomena occurring during LCF processes and to determine their main characteristics. Special attention is given to the LCF conditions inherent in Army structures (i.e., high cyclic or pulse loads reaching up to 90% of the ultimate strength in a fraction of a second). A summary of fatigue-related issues in laminate composites employed in Army land combat systems is presented. Analysis indicates that finite strain rate effects are important under LCF conditions and the pulse vibration fatigue (PVF). Fatigue damage mechanisms, evolution patterns of damage, and damage accumulation processes are singled out and thoroughly analyzed as the key mechanical phenomena contributing to the changes in the material damage state and the property degradation under fatigue conditions. Possible correlation between ballistic and LCF performance is discussed. Various models for damage accumulation and fatigue life predictions are reviewed. Recommendations for fundamental research in the areas relevant to the LCF of composite structures are included to establish a conceptual framework for the U.S. Army Research Laboratory (ARL) LCF Program.
