Book Description
Themethodologyfordesigninghigh-performancecompositestructuresisstill evo- ing. The complexity of the response of composite materials and the dif?culties in predicting the composite material properties from the basic properties of the c- stituents result in the need for a well-planned and exhaustive test program. The recommended practice to mitigate the technological risks associated with advanced composite materials is to substantiate the performance and durability of the design in a sequence of steps known as the Building Block Approach. The Building Block Approach ensures that cost and performance objectives are met by testing greater numbers of smaller, less expensive specimens. In this way, technology risks are assessed early in the program. In addition, the knowledge acquired at a given level of structural complexity is built up before progressing to a level of increased complexity. Achieving substantiation of structural performance by testing alone can be p- hibitively expensive because of the number of specimens and components required to characterize all material systems, loading scenarios and boundary conditions. Building Block Approachprogramscan achieve signi?cant cost reductionsby se- ing a synergy between testing and analysis. The more the development relies on analysis, the less expensive it becomes. The use of advanced computational models for the prediction of the mechanical response of composite structures can replace some of the mechanical tests and can signi?cantly reduce the cost of designing with composites while providing to the engineers the information necessary to achieve an optimized design.
Composite Structures 4
Author: I.H. Marshall
Publisher: Springer Science & Business Media
ISBN: 9400934556
Category : Technology & Engineering
Languages : en
Pages : 648
Book Description
The papers contained herein were presented at the Fourth International Conference on Composite Structures (ICCS/4) held at Paisley ColIege of Technology, Scotland in July 1987. The Conference was organised and sponsored by Paisley College of Technology. It was co-sponsored by the Scottish Development Agency, the National Engineering Laboratory, the US Air Force European Office of Aerospace Research and Development and the US Army Research, Development and Standardisation Group- UK. It forms a natural and ongoing progression from the highly successful First, Second and Third International Conferences on Composite Structures (ICCS/I, ICCS/2 and ICCS/3) held at Paisley in 1981, 1983 and 1985 respectively. There is little doubt that composite materials are rightfulIy claiming a prominent role in structural engineering in the widest sense. Moreover, the range and variety of useful composites has expanded to a level inconceivable a decade ago. However, it is also true that this increasing utilisation has generated an enhanced awareness of the manifold factors which dictate the integrity of composite structures. This is indeed a healthy attitude to a relatively new dimension in structural engineering which will have an increasingly dominant role as the century progresses. Both the diversity of application of composites in structural engineering and the endeavours which wilI ensure their fitness for purpose are reflected herein.

Optimisation of Composite Structures Design
Author: A Miravete
Publisher: Elsevier
ISBN: 0857092979
Category : Technology & Engineering
Languages : en
Pages : 213
Book Description
Composite materials have been used more and more during the last decade to lighten structures. But until now, there has been no clear way of establishing how to design properly optimised laminated composite plates with no reduction in strength. Most modern references lack adequate information for the designer wanting to tailor or synthesise a design. This exciting package offers a solution. It relates the theory of composite materials to real life and provides 'rules' for designing composites structures properly and in an optimum way.In the book, Professor Miravete demonstrates the optimisation of beams, plates and sandwich constructions in the designs of advanced composite materials. He also illustrates optimal material systems, fibre orientations and lay-up through functions of geometry, load type and boundary conditions. The associates software, on two disks, will enableusers to adapt the information to their own requirements and is very user-friendly with helpful manuals. This will be an essential package for designers and engineers in a wide range of areas, from aeronautics to automotive andmarine as well as general industry.Chapter 1 provides a general background on composite materials.Chapters 2, 3, 4, and 5 are concerned with constant thickness composite structures, and provide a survey of various design methodologies of shells, plates and sandwich constructions.Chapters 6, 7, 8 and 9 examine variable thickness composite structures, and consider beams, plates and sandwiches. - A completemanual for anyone concerned with designing composite structures - Includes book and used-friendly software - Can be easily applied to any area - aeronautics, automotive, marine or general industry

ICCS20 - 20th International Conference on Composite Structures
Author: Nicholas Fantuzzi
Publisher: Società Editrice Esculapio
ISBN: 8893850419
Category : Technology & Engineering
Languages : en
Pages : 352
Book Description
Composite materials have aroused a great interest over the last few decades, as proven by the huge number of scientific papers and industrial progress. The increase in the use of composite structures in different engineering practices justify the present international meeting where researches from every part of the globe can share and discuss the recent advancements regarding the use of structural components within advanced applications such as buckling, vibrations, repair, reinforcements, concrete, composite laminated materials and more recent metamaterials. Studies about composite structures are truly multidisciplinary and the given contributions can help other researches and professional engineers in their own field. This Conference is suitable as a reference for engineers and scientists working in the professional field, in the industry and the academia and it gives the possibility to share recent advancements in different engineering practices to the outside world. This book aims to collect selected plenary and key-note lectures of this International Conference. For this reason, the establishment of this 20th edition of International Conference on Composite Structures has appeared appropriate to continue what has been begun during the previous editions. ICCS wants to be an occasion for many researchers from each part of the globe to meet and discuss about the recent advancements regarding the use of composite structures, sandwich panels, nanotechnology, bio-composites, delamination and fracture, experimental methods, manufacturing and other countless topics that have filled many sessions during this conference. As a proof of this event, which has taken place in Paris (France), selected plenary and key-note lectures have been collected in the present book.

Optimization of Large Structural Systems

Category : Technology & Engineering
Languages : en
Pages : 1201
Book Description
G.I.N. Rozvany ASI Director, Professor of Structural Design, FB 10, Essen University, Essen, Germany Structural optimization deals with the optimal design of all systems that consist, at least partially, of solids and are subject to stresses and deformations. This inte grated discipline plays an increasingly important role in all branches of technology, including aerospace, structural, mechanical, civil and chemical engineering as well as energy generation and building technology. In fact, the design of most man made objects, ranging from space-ships and long-span bridges to tennis rackets and artificial organs, can be improved considerably if human intuition is enhanced by means of computer-aided, systematic decisions. In analysing highly complex structural systems in practice, discretization is un avoidable because closed-form analytical solutions are only available for relatively simple, idealized problems. To keep discretization errors to a minimum, it is de sirable to use a relatively large number of elements. Modern computer technology enables us to analyse systems with many thousand degrees of freedom. In the optimization of structural systems, however, most currently available methods are restricted to at most a few hundred variables or a few hundred active constraints.

EPMESC VII
Author: E. Arantes e Oliveira
Publisher: Elsevier
ISBN: 0080983758
Category : Computers
Languages : en
Pages : 798
Book Description
The first EPMESC Conference took place in 1985. It was during the Conference, recognising the success it had been, that the promoters decided to organise other EPMESC conferences, giving birth to a new series of international meetings devoted to computational methods in engineering. The variety of subjects covered by the papers submitted to the 7th Conference demonstrates how much computational methods expanded and became richer in their applications to Science and Technology. New paradigms are being cultivated as non-numerical applications started to compete with the more traditional numerical ones. The scientific and technological communities to which the EPMESC Conferences used to be addressed themselves have changed.The two-volume Proceedings that we achieved to gather represent many of the interesting developments that are taking place, not only in the Asia Pacific Region, but also in some other scientifically advanced parts of the World, and cover a vast list of subjects grouped under the following headings: Applied Mathematics; Physics and Materials Science; Solid Mechanics; Finite Element and Boundary Element Methods; Structural Analysis; Structural Dynamics and Earthquake Engineering; Structural Engineering; Reinforced Concrete; Knowledge-Based Systems; Artificial Neural Networks and Genetic Algorithms; Computer-Aided Instruction; Computer-Aided Design and Computer-Aided Engineering; Geographic Information Systems; Environmental Applications; Road Engineering; Geotechnics; Soil Mechanics; Fluid Mechanics and Hydraulics.Two hundred and fifty one summaries were accepted, many of them with comments and restrictions, by the Programme Committee.From these, 153 papers resulted, many of them from Portuguese and Chinese origin, that were submitted to the revision of an international panel of referees from Australia, Belgium, Brazil, China, Italy, Macao, Portugal, Switzerland, United Kingdom and United States, to which we gladly acknowledge our gratitude and appreciation.
