Book Synopsis Fusion Bonding of Polymer Composites by : C. Ageorges
Download or read book Fusion Bonding of Polymer Composites written by C. Ageorges and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusion bonding is one of the three methods available for joining composite and dissimilar materials. While the other two, mechanical fastening and adhesion bonding, have been the subject of wide coverage both in textbooks and monographs, fusion bonding is covered here substantially for the first time. Fusion bonding offers a number of advantages over traditional joining techniques and it is anticipated that its use will increase dramatically in the future because of the rise in the use of thermoplastic matrix composites and the growing necessity for recyclability of engineering assemblies. Fusion Bonding of Polymer Composites provides an in-depth understanding of the physical mechanisms involved in the fusion bonding process, covering such topics as: - heat transfer in fusion bonding; - modelling thermal degradation; - consolidation mechanisms; - crystallisation kinetics; - processing-microstructure-property relationship; - full-scale fusion bonding; - fusion bonding of thermosetting composite/thermoplastic composite and metal/thermoplastic joints. The book focuses on one practical case study using the resistance welding process. This example exposes the reader to the development of processing windows for a novel manufacturing process including the use of experimental test programmes and modelling strategies.
Book Synopsis Failure Analysis and Fractography of Polymer Composites by : Emile Greenhalgh
Download or read book Failure Analysis and Fractography of Polymer Composites written by Emile Greenhalgh and published by Elsevier. This book was released on 2009-09-28 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Book Synopsis The Virtual Crack Closure Technique: History, Approach and Applications by : Ronald Krueger
Download or read book The Virtual Crack Closure Technique: History, Approach and Applications written by Ronald Krueger and published by . This book was released on 2002 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of the virtual crack closure technique is presented. The approach used is discussed, the history summarized, and insight into its applications provided. Equations for two-dimensional quadrilateral elements with linear and quadratic shape functions are given. Formula for applying the technique in conjuction with three-dimensional solid elements as well as plate/shell elements are also provided. Necessary modifications for the use of the method with geometrically nonlinear finite element analysis and corrections required for elements at the crack tip with different lengths and widths are discussed. The problems associated with cracks or delaminations propagating between different materials are mentioned briefly, as well as a strategy to minimize these problems. Due to an increased interest in using a fracture mechanics based approach to assess the damage tolerance of composite structures in the design phase and during certification, the engineering problems selected as examples and given as references focus on the application of the technique to components made of composite materials.
Book Synopsis Stress Analysis of Fiber-reinforced Composite Materials by : M. W. Hyer
Download or read book Stress Analysis of Fiber-reinforced Composite Materials written by M. W. Hyer and published by DEStech Publications, Inc. This book was released on 2009 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: Updated and improved, Stress Analysis of Fiber-Reinforced Composite Materials, Hyer's work remains the definitive introduction to the use of mechanics to understand stresses in composites caused by deformations, loading, and temperature changes. In contrast to a materials science approach, Hyer emphasizes the micromechanics of stress and deformation for composite material analysis. The book provides invaluable analytic tools for students and engineers seeking to understand composite properties and failure limits. A key feature is a series of analytic problems continuing throughout the text, starting from relatively simple problems, which are built up step-by-step with accompanying calculations. The problem series uses the same material properties, so the impact of the elastic and thermal expansion properties for a single-layer of FR material on the stress, strains, elastic properties, thermal expansion and failure stress of cross-ply and angle-ply symmetric and unsymmetric laminates can be evaluated. The book shows how thermally induced stresses and strains due to curing, add to or subtract from those due to applied loads.Another important element, and one unique to this book, is an emphasis on the difference between specifying the applied loads, i.e., force and moment results, often the case in practice, versus specifying strains and curvatures and determining the subsequent stresses and force and moment results. This represents a fundamental distinction in solid mechanics.

Book Synopsis Nonupdating Methods for the Characterization of Nonlinear Stress-strain and Delamination Fracture Properties of Fiber Reinforced Composites by : Bastiaan Corstiaan Wouter van der Vossen
Download or read book Nonupdating Methods for the Characterization of Nonlinear Stress-strain and Delamination Fracture Properties of Fiber Reinforced Composites written by Bastiaan Corstiaan Wouter van der Vossen and published by . This book was released on 2021 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts to develop strength and life prediction analysis tools for aircraft composite structures have shown a great need to understand the complexity and interaction of failure modes. Many failure models are highly sensitive to transverse nonlinear shear stress-strain and delamination fracture properties, which are notoriously hard to measure. Without proper input parameters, life predictions analyses will not be successful. The objective of this work was to accurately characterize these mechanical properties of carbon fiber reinforced polymer composites through advanced experimental methods. Full-field noncontact deformation measurements using Digital Image Correlation are used to quantify all surface strains components, enabling the design of experiments subject to complex loading. The presented splined-based optimization techniques link measured strains to applied loading, converging to accurate material properties without ad hoc assumptions on the material model. These methods improve on first-order closed-form and iterative numerical solutions due to flexibility and accuracy without the computational expense. Applications of the optimization model on the Short Beam Shear and Thick Adherend shear tests proved the usefulness of these methods. Full three-dimensional characterization of selected carbon fiber-reinforced polymer composites is presented with a discussion of the applicability of simplifying assumptions on the material model. This experimental program showed that the assumption of transverse anisotropy must be verified, as it may be inaccurate depending on the material. Furthermore, large shear strain response of IM7/8552 UD specimens has been measured by asymmetric three-point bending test. Applicability of the common D3518 ±45 degree off-axis tensile test was also deliberated. Shear stress-strain response measured from D3518 specimens disagrees with the Short Beam Shear and Small Plate Twist test results after about 5000 microstrain. This conclusion was shown to be influenced by the specimens' stacking sequence and microdamage which develops well before damage can be spotted in X-ray Computed Tomography reconstructions. High-magnification deformation measurements are applied to directly measure cohesive laws in precracked Double Cantilever Beam and Thick Adherend shear specimens. Supported by non-destructive in situ crack front measurements by Computed Tomography, the loaded crack tip displacements are directly related to the J-integral. The derived traction-separation law is verified by the excellent agreement of the global response between cohesive model Finite Element Analysis and measurements. This study was the first application of the direct measurement of mode II traction-separation law in Thick Adherend shear specimens.

Book Synopsis Initiation and Growth of Mode II Delamination in Toughened Composites by : AJ. Russell
Download or read book Initiation and Growth of Mode II Delamination in Toughened Composites written by AJ. Russell and published by . This book was released on 1991 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origins of nonlinearity in the Mode II delamination fracture of three organic matrix, carbon fiber composite materials was investigated. This was accomplished by testing specimens with different types of starter cracks and by loading and unloading these specimens several times so that the change in nonlinearity as the delaminations grew could be measured. The load at which crack growth initiated was determined by acoustic emission. Slow crack growth was found to be the principal cause of nonlinearity in the materials tested. The crack velocity obeyed the same power law dependence on GII as has been observed for slow crack growth in visco-elastic polymers. For the first loading from the end of the starter cracks, plastic deformation at the crack tip also contributed to the nonlinearity. Other sources of nonlinearity included an increasing fracture resistance in one of the materials as well as problems associated with producing a clean, sharp starter notch with a straight crack front. The implications of these findings to the use of linear elastic fracture mechanics for predicting delamination behavior of these materials and to the measurement of Mode II interlaminar fracture toughness are also discussed.

Book Synopsis Fracture Mechanics Testing Methods for Polymers, Adhesives and Composites by : D.R. Moore
Download or read book Fracture Mechanics Testing Methods for Polymers, Adhesives and Composites written by D.R. Moore and published by Elsevier. This book was released on 2001-03-09 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an overview of ESIS Technical Committee 4's activities since the mid-1980s. A wide range of tests is described and the numerous authors is a reflection of the wide and enthusiastic support we have had. With the establishment of the Technical Committee 4, two major areas were identified as appropriate for the activity. Firstly there was an urgent need for standard, fracture mechanics based, test methods to be designed for polymers and composites. A good deal of academic work had been done, but the usefulness to industry was limited by the lack of agreed standards. Secondly there was a perceived need to explore the use of such data in the design of plastic parts. Some modest efforts were made in early meetings to explore this, but little progress was made. In contrast things moved along briskly in the standards work and this has dominated the activity for the last fourteen years. The design issue remains a future goal.
