This book was released on 2011-07-14 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first comprehensive review of its kind on the long-term behaviour of composite materials and structures subjected to time variable mechanical, thermal, and chemical influences, a subject of critical importance to the design, development, and certification of high performance engineering structures. Specific topics examined include damage, damage characterization, and damage mechanics; fatigue testing and evaluation; fatigue behaviour of short and long fibre reinforced polymer and metal matrix materials; viscoelastic and moisture effects; delamination; statistical considerations; the modeling of cumulative damage development; and life prediction. The volume provides an extensive presentation of data, discussions, and comparisons on the behaviour of the major types of material systems in current use, as well as extensive analysis and modeling (including the first presentation of work not found elsewhere). The book will be of special interest to engineers concerned with reliability, maintainability, safety, certification, and damage tolerance; to materials developers concerned with making materials for long-term service, especially under severe loads and environments, and to lecturers, students, and researchers involved in material system design, performance, solid mechanics, fatigue, durability, and composite materials. The scope of the work extends from entry level material to the frontiers of the subject.

This book was released on 1983 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is Vol. I of a 2-part final report on the activities which were conducted under Contract No. F33615-81-3225. The general objective of this program was to investigate the precise nature of the damage events caused by cyclic (fatigue) loading of composite laminates that are directly related to fracture of those laminates, to develop a conceptual understanding of how those damage events reduce the residual strength of the laminates, and to determine how the collective damage condition following long-term cyclic loading precipitates the final fracture event. The program was conducted in four phases: (1) the development of fatigue damage during long-term cyclic loading was investigated in such a way that the damage events which occur quite late in the fatigue life of the material, just prior to fracture, were identified and characterized; (2) the special contribution and nature of fiber fracture was investigated; (3) the nature of the collective damage condition which precipitates the fracture event under long-term fatigue loading was investigated; (4) a philosophy of fracture in composite laminates following severe damage development due to cyclic loading was developed. A wide variety of destructive and nondestructive experimental evaluation schemes were used in the program, and several analytical efforts were conducted to support the experimental activities.

Download or read book A Combined Material and Structural Approach to Fatigue Failure Analysis of Bolted Thick Composite Laminates written by Hamid Hamidi and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the existing works on fatigue of long fiber composite laminates approach the problem from the material point of view. These works have also been mainly on thin laminates. This is because the laminates (particularly unidirectional laminates) are considered to be homogeneous and uniform. This may or may not be true because of the heterogeneous nature of the composite (consisting of fibers and matrix and interface), and the significant variability which gives rise to random spatial variation in the properties. A composite laminate is actually both a structure and a material. For thin laminates, the structural aspect is usually scanned over and only the material aspect is focused on. This gives rise to the expectation that the laminate should behave as a material (with good homogeneity and with little variability). This has resulted in failure of many failure criteria. The importance of the structural aspect is more evident for the case of thick laminates, subjected to flexural loading while being constrained by bolts. To study the fatigue behavior of such materials (and structures), both the structural aspects and the material aspects must be taken into consideration. This is the subject of study of the present research. A combined material and structural approach, namely, the application of coupon level material properties (material level) into the 3D finite element model (structural level) is introduced and applied. By doing this, it examines the behavior of thick unidirectional glass/epoxy laminates subjected to flexural loads while being constrained by bolts. Both theoretical and experimental studies are carried out to validate each other. The theoretical part consists first of structural analysis which provides the locations of potential failure. This is followed by the application of fatigue failure criteria at these locations. Good correspondence is seen between the experimental and the theoretical results. The agreement between the results of experiments with those of developed fatigue progressive damage modeling (FPDM) shows that the combined material and structural approach is suitable to study the fatigue behavior of thick composite laminates subjected to bolt loads.

Download or read book Failure Analysis of Composite Materials with Manufacturing Defects written by Ramesh Talreja and published by CRC Press. This book was released on 2024-02-16 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: In contrast to metals, a composite material acquires an internal structure where the imprint of its manufacturing process history is a significant part of the internal structure’s makeup and in many cases determines how the material responds to external impulses. The performance for which a composite material is designed must therefore be assessed with due consideration to the manufacturing-induced features in the material volume. Failure theories based on homogenized composites cannot deliver reliable methodologies for performance assessment. This book details approaches that depart from traditional treatments by accounting for manufacturing defects in composite materials. It discusses how manufacturing defects are produced and how they affect the performance of composite materials. Serves as the only book to bring knowledge on manufacturing and failure modeling together in a coherent manner. Guides readers on mechanisms-based modeling with a focus on defects. Treats statistical simulation of microstructure with defects aimed at physical modeling. Covers manufacturing methods for polymer matrix composites. Describes failure modes in unidirectional composites and laminates in the presence of defects. Discusses fatigue damage in the presence of defects. This book is aimed at researchers in industry and academia in aerospace engineering, mechanical engineering, and materials science and engineering. It also serves as a reference for students taking advanced courses in composite materials.

This book was released on 2008-01-08 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The course deals with the crucial central question: how can one predict the evolution of damage up to and including final fracture ?Emerging yet mature answers will be presented. First, a description of today's common approaches in industrial environments will be given, along with their limits regarding the design and calculation of stratified composite structures. The course also emphasizes the damage mesomodel initiated at LMT-Cachan and used today in a number of calculation codes. This advanced yet pragmatic tool for the prediction of damage in stratified materials has become mature thanks particularly to the works of LMT-Cachan on its relation to micromechanics, EADS-Innovation Works on its identification, and DLR on its application to impact and crash problems. The course aims to give engineers and researchers the most complete view possible of the state-of-the-art and emerging techniques in damage prediction and failure analysis of laminated composite structures.

Available in PDF, EPUB and Kindle. Book excerpt: From the Author's PrefaceThe objective of this book is to provide a thorough and systematic study of the problem of laminated composites containing stress concentrations. Stress concentrations are introduced in laminated plates in the forms of circular holes, elliptical openings and straight cracks. These forms of cutouts have many practical applications, and are familiar to most engineers. Stress concentrations exist in all known structural components. Stress concentrations have great practical importance because they are normally the cause of failure. In addition to stress analyses of laminated composites, we need more fundamental understanding of the failure mode, the failure criterion, the effects on global laminate response, and the design of composites in the presence of stress concentrations. In this book, all the subjects studied are closely related to the problem of stress concentrations in laminated composites . . . . All the models are verified with many experimental results. The underlying objective of this comprehensive study is to give the readers an in-depth and thorough understanding of the problem of stress concentrations in composites. This book is the first to address the problem of laminated composites containing stress concentrations in a systematic way.

This book was released on 2016 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: In-situ fatigue damage diagnosis and prognosis is a challenging problem for both metallic and composite materials and structures. There are various uncertainties arising from material properties, component geometries, measurement noise, feature extraction techniques, and modeling errors. It is essential to manage and incorporate these uncertainties in order to achieve accurate damage detection and remaining useful life (RUL) prediction. The aim of this study is to develop an integrated fatigue damage diagnosis and prognosis framework for both metallic and composite materials. First, Lamb waves are used as the in-situ damage detection technique to interrogate the damaged structures. Both experimental and numerical analysis for the Lamb wave propagation within aluminum are conducted. The RUL of lap joints under variable and constant fatigue loading is predicted using the Bayesian updating by incorporating damage detection information and various sources of uncertainties. Following this, the effect of matrix cracking and delamination in composite laminates on the Lamb wave propagation is investigated and a generalized probabilistic delamination size and location detection framework using Bayesian imaging method (BIM) is proposed and validated using the composite fatigue testing data. The RUL of the open-hole specimen is predicted using the overall stiffness degradation under fatigue loading. Next, the adjoint method-based damage detection framework is proposed considering the physics of heat conduction or elastic wave propagation. Different from the classical wave propagation-based method, the received signal under pristine condition is not necessary for estimating the damage information. This method can be successfully used for arbitrary damage location and shape profiling for any materials with higher accuracy and resolution. Finally, some conclusions and future work are generated based on the current investigation.
