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 Impact Response and Dynamic Failure of Composites and Laminate Materials written by Jang Kyo Kim and published by Trans Tech Publications Ltd. This book was released on 1997-09-04 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many engineering applications of composite and laminate materials, damage and failure can be caused by impact of various types. Low-velocity impact is potentially dangerous because it can produce extensive sub-surface delamination that may not be visible on the surface. High-velocity impact produced by projectiles, shock waves and fragments from exploding ammunition is a highly dynamic event, leading to the penetration or perforation of composites. All impact damage is detrimental to the mechanical and structural performance of composites. Accurate evaluation of the damaged state, and a fundamental understanding of the effect of damage upon the resultant properties are therefore essential for the proper design and application of composite materials. The strain-rate dependence of material behavior, fracture propagation and energy-absorbing capacity are also of paramount importance from both the materials science and structural mechanics perspectives.

Download or read book Low velocity Impact Analysis of Composite Repair Patches of Different Shapes written by Sarvesh Baliga and published by . This book was released on 2015 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area under crack for various structures can be effectively repaired by the use of composite materials. Low velocity impact can cause barely visible damage to the interior structure of laminated composite. These impacts can cause delamination in composite materials. In this study, a Finite Element Analysis was conducted using Abaqus/Explicit and the results of the analysis were compared to the experimental data from literature. E-gloss/epoxy composite laminate was subjected to a low velocity impact test. To study the effect of patch repair, a composite patch was applied on a cracked laminate and a low velocity impact was then conducted on this model. The FEW results were validated with the experimental data and an approach to model an ideal composite patch shape was conducted. Different patch shapes like square, rectangle, circle and ellipse were designed and analyzed on the crack, keeping the surface area of the patch common. All these patches were compared and an ideal patch shape was found for the model on the basis of stress concentration on the patch. Finally, a parametric study was performed considering the change in impactor speed and impactor material on the impact damage. Thus, this research work readily demonstrated the effectiveness of finite element analysis of low velocity impact.
Download or read book Impact Behaviour of Fibre reinforced Composite Materials and Structures written by S.R. Reid and published by CRC Press. This book was released on 2000-10-31 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the early, pioneering work on the properties of composites under impact is still conceptually relevant, yet the results of many such analyses are outdated. The accuracy of these results depend specifically on the materials used (fibre, resin), interface, and method of fabrication. Development of new materials, cost effective design, and analysis and prediction of structural behaviour have all established a need for timely, wide ranging research on impact behaviour. Impact Behaviour of Fibre-Reinforced Composite Materials and Structures brings together - for the first time - state-of-the-art research from the most recent works of leading, international experts. An important new study, this book extensively investigates impact response, damage tolerance, and failure of fibre-reinforced composite materials and structure, from a number of expert viewpoints. This book explores the nature of modern polymer composites based on glass, carbon, aramid, ceramic and polymer fibres in a polymer matrix, and details various ways of analysing the impact process. Impact Behaviour of Fibre-Reinforced Composite Materials and Structures will prove itself a valuable tool for research and development engineers, structural engineers, materials scientists, designers, and students and researchers of related disciplines.
