This book was released on 2005 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through feature-based acoustic emission (AE) analysis and supervised clustering, data acquired during monotonic loading can reveal damage initiation, development, and accumulation within a specimen. In this work, AE analysis using a supervised pattern recognition method is carried out on specimens with co-cured composite joints of single lap and single nested overlap configurations. Correlation with physical observations from other techniques suggests that the resulting clusters may be associated with specific damage modes and failure mechanisms.

This book was released on 2005 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research investigates two co-cured joint configurations, the conventional single lap joint, and the modified single nested overlap joint, which is obtained by a minor alteration of the former configuration. A systematic comparison of damage initiation, damage progression mechanisms, and failure modes of co-cured joint specimens under quasi-static tensile loading is carried out. Several investigation methods are used including acoustic emission, visual observation, optical microscopy, and X-ray radiography.

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 Identification of Fatigue Failure Modes in Carbon Fibre Reinforced Composites with the Energy Discriminating Acoustic Emission Method written by E. Aernoudt and published by . This book was released on 1991 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tension-tension fatigue of carbon fibre reinforced composite laminates is characterized by the initiation and growth of specific damage modes. A method was developed to study the AE-signals released from each individual damage source so that the growth of distinct fatigue damage modes could be monitored. The obtained results correlated well with the real damage extent of each individual damage mode. This is an improvement compared to the general information the total number of acoustic emission signals can give on the fatigue degradation of the specimens.

Download or read book Fatigue and Fracture of Adhesively Bonded Composite Joints written by Anastasios P. Vassilopoulos and published by Elsevier. This book was released on 2014-10-21 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Structural Health Monitoring Damage Detection Systems for Aerospace written by Markus G. R. Sause and published by Springer Nature. This book was released on 2021 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents established methods of structural health monitoring (SHM) and discusses their technological merit in the current aerospace environment. While the aerospace industry aims for weight reduction to improve fuel efficiency, reduce environmental impact, and to decrease maintenance time and operating costs, aircraft structures are often designed and built heavier than required in order to accommodate unpredictable failure. A way to overcome this approach is the use of SHM systems to detect the presence of defects. This book covers all major contemporary aerospace-relevant SHM methods, from the basics of each method to the various defect types that SHM is required to detect to discussion of signal processing developments alongside considerations of aerospace safety requirements. It will be of interest to professionals in industry and academic researchers alike, as well as engineering students.

This book was released on 2018-06-28 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of acoustic emission and acousto-ultrasonics to characterize impact damage in composite structures is being performed on both graphite epoxy and kevlar bottles. Further development of the acoustic emission methodology to include neural net analysis and/or other multivariate techniques will enhance the capability of the technique to identify failure mechanisms during fracture. The acousto-ultrasonics technique will be investigated to determine its ability to predict regions prone to failure prior to the burst tests. The combination of the two methods will allow for simple nondestructive tests to be capable of predicting the performance of a composite structure prior to being placed in service and during service.
