Available in PDF, EPUB and Kindle. Book excerpt: This book presents novel methods for the simulation of damage evolution in aerospace composites that will assist in predicting damage onset and growth and thus foster less conservative designs which realize the promised economic benefits of composite materials. The presented integrated numerical/experimental methodologies are capable of taking into account the presence of damage and its evolution in composite structures from the early phases of the design (conceptual design) through to the detailed finite element method analysis and verification phase. The book is based on the GARTEUR Research Project AG-32, which ran from 2007 to 2012, and documents the main results of that project. In addition, the state of the art in European projects on damage evolution in composites is reviewed. While the high specific strength and stiffness of composite materials make them suitable for aerospace structures, their sensitivity to damage means that designing with composites is a challenging task. The new approaches described here will prove invaluable in meeting that challenge.

Available in PDF, EPUB and Kindle. Book excerpt: Since the successful production of carbon fibers in early 1960s, composite materials have emerged as the materials of choice for general aviation aircraft, military aircraft, space launch vehicles, and unmanned air vehicles. This has revolutionized the aerospace industry due to their excellent mechanical and physical properties, as well as weight-reducing ability. The next- generation material development model should operate in an integrated computational environment, where new material development, manufacturability, and product design practice are seamlessly interconnected. Materials and Process Modeling of Aerospace Composites reports recent developments on materials and processes of aerospace composites by using computational modeling, covering the following aspects: • The historical uses of composites in aerospace industry, documenting in detail the early usage of composite materials on Premier I by Raytheon to recent full-scale applications of composites on large commercial aircraft by Boeing and Airbus. • An overview on the classifications of composites used in aerospace industry, ranging from conventional glass- fiber reinforced composites to advanced graphene nanocomposites. • The recent work on computational material engineering on aerospace composite materials, including fundamental computational frame work and case studies on the modeling of materials and processes

Book excerpt: Composite Materials in Aerospace Design is one of six titles in a coherent and definitive series dedicated to advanced composite materials research, development and usage in the former Soviet Union. Much of the information presented has been classified until recently. Thus each volume provides a unique insight into hitherto unknown research and development data. This volume deals with the design philosophy and methodology used to produce primary and secondary load bearing composite structures with high life expectancies. The underlying theme is of extensive advanced composites research and development programs in aircraft and spacecraft applications, including the space orbital ship `BURAN'. The applicability of much of this work to other market sectors, such as automotive, shipbuilding and sporting goods is also examined in some detail. The text starts by describing typical structures for which composites may be used in this area and some of the basic requirements from the materials being used. Design of components with composite materials is then discussed, with specific reference to case studies. This is followed by discussion and results from evaluation of finished structures and components, methods of joining with conventional materials and finally, non-destructive testing methods and forecasting of the performance of the composite materials and the structures which they form. Composite Materials in Aerospace Design will be of interest to anyone researching or developing in composite materials science and technology, as well as design and aerospace engineers, both in industry and universities.

Available in PDF, EPUB and Kindle. Book excerpt: Aerospace structural design, especially for large aircraft, is an empirical pursuit dominated by rules of thumb and often-painful service experiences. Expertise on traditional materials is not transferable to “new materials, processes and structural concepts. This is because it is not based on or derived from well-defined measures of safety. This book addresses the need for safe innovation based on practical, explicit structural safety constraints for use in innovative structures of the future where guiding service experience is non-existent. The book covers new ground by the demonstration of ways to satisfy levels of safety by focusing on structural integrity; and complementing the lack of service experience with risk management, based on flexible inspection methods recognizing that safety is a function of time. Fundamentally the book shoes demonstrates how safety methods can be made available to the engineering community without requiring huge statistical databases to establish internal and external loads distributions for use in reliability analysis. An essential title for anyone working on structural integrity, or composite structures. It will be of equal interest to aerospace engineers and materials scientists working in academia, industry and government. Demonstrates a practically manageable way to produce safe innovation using composites in environments with no service experience New approach to a subject that has not previously been treated in a holistic manner This book could not have come at a more topical time, Boeing are currently launching the first commercial plane made entirely of composite materials The focus of this book is Composite Materials but other fields of innovation could be treated in the same manner

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.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this work was to investigate the fatigue damage mechanisms and to identify the influence of skin stacking sequence in carbon epoxy composite bonded skin/stringer constructions. A simple 4-point-bending test fixture originally designed for previously performed monotonic tests was used to evaluate the fatigue debonding mechanisms between the skin and the bonded frame when the dominant loading in the skin is flexure along the edge of the frame. The specimens consisted of a tapered flange, representing the stringer, bonded onto a skin. Based on the results of previous monotonic tests two different skin lay-ups in combination with one flange lay-up were investigated. The tests were performed at load levels corresponding to 40%, 50%, 60%, 70%, and 80% of the monotonic fracture loads. Microscopic investigations of the specimen edges were used to document the onset of matrix cracking and delamination, and subsequent fatigue delamination growth. Typical damage patterns for both specimen configurations were identified. The observations showed that failure initiated near the tip of the flange in the form of matrix cracks at one of two locations, one in the skin and one in the flange. The location of the 90 deg flange and skin plies relative to the bondline was identified as the dominant lay-up feature that controlled the location and onset of matrix cracking and subsequent delamination. The fatigue delamination growth experiments yielded matrix cracking and delamination onset as a function of fatigue cycles as well as delamination length as a function of the number of cycles.
