Available in PDF, EPUB and Kindle. Book excerpt: Constant amplitude tension-tension fatigue tests were conducted on AS4/3501-6 graphite epoxy (02/?2/-?2)s laminates, where ? was 15, 20, 25, or 30°. Fatigue tests were conducted at a frequency of 5 Hz and an R-ratio of 0.1. Dye penetrant-enhanced X-radiography was used to document the onset of matrix cracking in the central - ?° plies and the subsequent onset of local delaminations in the ?/-? interface at the intersection of the matrix cracks and the free edge.

Part 2 written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-08 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constant amplitude tension-tension fatigue tests were conducted on AS4/3501-6 graphite/epoxy (02/ theta sub 2/ -(theta sub 2))sub s laminates, where theta was 15, 20, 25, or 30 degrees. Fatigue tests were conducted at a frequency of 5 Hz and an R-ratio of 0.1. Dye penetrant enhanced x-radiography was used to document the onset of matrix cracking in the central -(theta) degree plies, and the subsequent onset of local delaminations in the theta/ -(theta) interface at the intersection of the matrix cracks and the free edge, as a function of the number of fatigue cycles. Two strain energy release rate solutions for local delamination from matrix cracks were derived: one for a local delamination growing from an angle ply matrix crack with a uniform delamination growing from an angle ply matrix crack with a triangular shaped delamination area that extended only partially into the laminate width from the free edge. Plots of G(max) vs. N were generated to assess the accuracy of these G solutions. The influence of residual thermal and moisture stresses on G were also quantified. However, a detailed analysis of the G components and a mixed-mode fatigue failure criterion for this material may be needed to predict the fatigue behavior of these laminates. Obrien, T.

Available in PDF, EPUB and Kindle. Book excerpt: Quasi-static tension tests were conducted on AS4/3501-6 graphite epoxy (02/?2/-?2)s laminates, where ? was 15, 20, 25, or 30°. Dye penetrant-enhanced X-radiography was used to document the onset of matrix cracking in the central - ?° plies and the onset of local delaminations in the ?/-? interface at the intersection of the matrix cracks and the free edge. Edge micrographs taken after the onset of damage were used to verify the location of the matrix cracks and local delaminations through the laminate thickness.

This book was released on 2018-07-08 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two different families of graphite/epoxy laminates with similar layups but different stacking sequences, (0, theta, -theta) sub s and (-theta/theta/0) sub s were analyzed using three-dimensional finite element analysis for theta = 15 and 30 degrees. Delaminations were modeled in the -theta/theta interface, bounded by a matrix crack and the stress free edge. The total strain energy release rate, G, along the delamination front was computed using three different techniques: the virtual crack closure technique (VCCT), the equivalent domain Integral (EDI) technique, and a global energy balance technique. The opening fracture mode component of the strain energy release rate, Gl, along the delamination front was also computed for various delamination lengths using VCCT. The effect of residual thermal and moisture stresses on G was evaluated. Salpekar, Satish A. and Obrien, T. Kevin and Shivakumar, K. N. Langley Research Center.

Download or read book Multi-Scale Modelling of Composite Material Systems written by C Soutis and published by Elsevier. This book was released on 2005-08-29 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most important and exciting areas of composites research is the development of modelling techniques to predict the response of composite materials to different types of stress. Predictive modelling provides the opportunity both to understand better how composites behave in different conditions and to develop materials with enhanced performance for particular industrial applications. Multi-scale modelling of composite material systems summarises the key research in this area and its implications for industry.The book covers modelling approaches ranging from the micron to the metre in scale, and from the single fibre to complete composite structures. Individual chapters discuss a variety of material types from laminates and fibre-reinforced composites to monolithic and sandwich composites. They also analyse a range of types of stress and stress response from fracture and impact to wear and fatigue. Authors also discuss the strengths and weaknesses of particular models.With its distinguished editors and international team of contributors, Multi-scale modelling of composite material systems is a standard reference for both academics and manufacturers in such areas as aerospace, automotive and civil engineering. Extensive coverage of this important and exciting area of composites research Understand how composites behave in different circumstances Compiled by an expert panel of authors and editors
