This book was released on 1982 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of stacking sequence on damage growth and failure modes in composite laminates is discussed. Tests were conducted on AS/3501-6 graphite/epoxy coupons with four different stacking sequences. All laminates had the same percentage of 0, 90, and ±45 degree plies. Constant amplitude fatigue tests were performed at R (minimum to maximum stress ratio) = -1.0 and -?. The specimens were periodically taken out of the testing machine and subjected to nondestructive inspection using X-ray radiography with diiodobutane.

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.

This book was released on 1991 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residual strength of an impacted composite laminate is dependent on details of the damage state. Stacking sequence was varied to judge its effect on damage caused by low-velocity impact. This was done for quasi-isotropic layups of a toughened composite material. Experimental observations on changes in the impact damage state and post-impact compressive performance were presented for seven different laminate stacking sequences. The applicability and limitations of analysis compared to experimental results were also discussed.

This book was released on 2014-04-21 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advantages of composite materials include a high specific strength and stiffness, formability, and a comparative resistance to fatigue cracking and corrosion. However, not forsaking these advantages, composite materials are prone to a wide range of defects and damage that can significantly reduce the residual strength and stiffness of a structure or result in unfavorable load paths. Emphasizing defect identification and restitution, Defects and Damage in Composite Materials and Structures explains how defects and damage in composite materials and structures impact composite component performance. Providing ready access to an extensive, descriptive list of defects and damage types, this must-have reference: Examines defect criticality in composite structures Recommends repair actions to restore structural integrity Discusses failure modes and mechanisms of composites due to defects Reviews NDI processes for finding and identifying defects in composite materials Relating defect detection methods to defect type, the author merges his experience in the field of in-service activities for composite airframe maintenance and repair with indispensable reports and articles on defects and damage in advanced composite materials from the last 50 years.

Download or read book A Comparison of Discrete Damage Modeling Methods written by Joseph Keith Novak and published by . This book was released on 2019 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discrete damage modeling of composite failure mechanisms including delamination, matrix cracking, and their interactions was performed for the skin laminate in a composite pi-joint test specimen subject to a pull-off load. The skin laminate stacking sequence was varied, and the pull-off load and path of predicted damage were recorded. Within the study two discrete damage modeling tools were used, Abaqus XFEM with a LaRC05 built-in user subroutine and BSAM. Both tools implement failure criteria developed at the NASA Langley Research Center (LaRC) to predict the location of damage initiation and both tools use similar cohesive zone models to model damage accumulation and crack propagation of matrix cracks and delaminations. However, the tools differ in their approach of modeling mesh independent matrix cracks in the bulk lamina. Abaqus XFEM implements a standard formulation of the eXtended Finite Element Method (XFEM), whereas BSAM uses a Regularized eXtended Finite Element Method (RxFEM). The results of the discrete damage modeling tools were compared with baseline models that only considered interface damage. It was shown that by including effects of matrix cracks the peak pull-off loads were considerably reduced. Moreover, the predicted failure path between the baseline and discrete damage models were vastly different. Comparing the discrete damage models, the prediction of the first damage site was in agreement, and the paths of predicted damage and peak pull-off loads were similar. The convergence of the BSAM solver was found to be superior as the Abaqus solver would diverge when damage occurred at multiple sites and the interaction became complex.

This book was released on 2019-10-08 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

This book was released on 2022-06-10 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: With his work, Martin Nebe provides principal insights into the mechanical response of composite pressure vessels subjected to internal pressure. By establishing and validating an in situ characterization methodology, the vessel’s geometry, its deformation behavior and the damage evolution process under internal pressure loading become accessible. This not only permits to trace back certain phenomena related to the manufacturing of these components but also allows to verify analytical and numerical modeling strategies. The exercised correlation of predicted and experimental results delivers detailed insights into design considerations to composite pressure vessels such as the definition of stacking sequence. The transfer of knowledge to a fullscale vessel geometry, which is representative for the use in fuel cell electric vehicles underlines the industrial application of this work. By combining numerical modeling, filament winding and experimental characterization, this work provides a sound foundation for future developments in the area of composite pressure vessels used for hydrogen storage.
