Download or read book Defects and Damage in Composite Materials and Structures written by Rikard Benton Heslehurst and published by CRC Press. 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 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.
Download or read book Structural Health Monitoring of Large Structures Using Acoustic Emission Case Histories written by Kanji Ono and published by MDPI. This book was released on 2020-11-23 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustic emission (AE) techniques have successfully been used for assuring the structural integrity of large rocket motorcases since 1963, and their uses have expanded to ever larger structures, especially as structural health monitoring (SHM) of large structures has become the most urgent task for engineering communities around the world. The needs for advanced AE monitoring methods are felt keenly by those dealing with aging infrastructures. Many publications have appeared covering various aspects of AE techniques, but documentation of actual applications of AE techniques has been mostly limited to reports of successful results without technical details that allow objective evaluation of the results. There are some exceptions in the literature. In this Special Issue of the Acoustics section of Applied Sciences, we seek contributions covering these exceptions cited here. Here, we seek contributions describing case histories of AE applications to large structures that have achieved the goals of SHM by providing adequate technical information supporting the success stories. Types of structures can include aerospace and geological structures, bridges, buildings, factories, maritime facilities, off-shore structures, etc. Experiences with AE monitoring methods designed and proven for large stru

Download or read book Structural Health Monitoring For Advanced Composite Structures written by M H Ferri Aliabadi and published by World Scientific. This book was released on 2017-12-18 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural health monitoring (SHM) is a relatively new and alternative way of non-destructive inspection (NDI). It is the process of implementing a damage detection and characterization strategy for composite structures. The basis of SHM is the application of permanent fixed sensors on a structure, combined with minimum manual intervention to monitor its structural integrity. These sensors detect changes to the material and/or geometric properties of a structural system, including changes to the boundary conditions and system connectivity, which adversely affect the system's performance.This book's primary focus is on the diagnostics element of SHM, namely damage detection in composite structures. The techniques covered include the use of Piezoelectric transducers for active and passive Ultrasonics guided waves and electromechanical impedance measurements, and fiber optic sensors for strain sensing. It also includes numerical modeling of wave propagation in composite structures. Contributed chapters written by leading researchers in the field describe each of these techniques, making it a key text for researchers and NDI practitioners as well as postgraduate students in a number of specialties including materials, aerospace, mechanical and computational engineering.

This book was released on 2015-06-01 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ingenuity and visibility of NASA space programs, such as the max launch abort system (MLAs), are sparking the creativity, knowledge transfer, and unique applications of revolutionary technologies in areas such as aerospace, wind energy, transportation, oil, safety, and civil infrastructure. Lightweight, high-strength, carbon-fiber composites materials, vacuum-assisted resin transfer molding, smart sensors, out-of-autoclave curing of autoclave composites, unified structures, structural health monitoring systems, smart phone/RFID tracking, determinant assembly, forensic engineering, and the digital tapestry that ties everything together are just a few of the technological advances perfected in NASA’s programs. Successful composites technology transfer takes the discussion of these technologies to the next level — addressing the advantages and challenges to their more widespread industrial application. Readers will get insight into how high-strength, carbon-fiber composites and its related technologies are making inroads into products such as commercial airplane seats and carts, turbine blades, firefighting equipment, trucks, buses, lifting and support devices, and containers. The author shares breakthrough thinking on other potential applications, such as a new lighter than air ship, prototype vehicles, driver health and safety, firefighter safety, and bridge infrastructure safety and health monitoring. According to Foreword author, Tim Shinbara, vice president of manufacturing technology at AMT (Association for Manufacturing Technology), “...it is of considerable value to search out, discover, and digest resources such as this book in an effort to continually improve the lens by which we innovate.” Aside from new product innovations, extension of the manufacturing technologies, and processes described herein have the potential to not only add new functionality or modify the existing functionality of existing products and systems, but in many cases, adoption would require minimal effort from the manufacturing enterprise.
