Book Description
Optimal design of various types of symmetric laminates for T300/5208 graphite epoxy composites was investigated under the first ply failure criteria. The symmetric laminates considered include continuous laminate and angle ply laminate. The optimal design angles 0 were obtained and presented in graphic form as functions of the loading conditions (N1, N2, N6). The results presented here are directly useful for designers for making a choice of composites for optimal performance. (Author).

Book Description
From the Author's PrefaceThe objective of this book is to provide a thorough and systematic study of the problem of laminated composites containing stress concentrations. Stress concentrations are introduced in laminated plates in the forms of circular holes, elliptical openings and straight cracks. These forms of cutouts have many practical applications, and are familiar to most engineers. Stress concentrations exist in all known structural components. Stress concentrations have great practical importance because they are normally the cause of failure. In addition to stress analyses of laminated composites, we need more fundamental understanding of the failure mode, the failure criterion, the effects on global laminate response, and the design of composites in the presence of stress concentrations. In this book, all the subjects studied are closely related to the problem of stress concentrations in laminated composites . . . . All the models are verified with many experimental results. The underlying objective of this comprehensive study is to give the readers an in-depth and thorough understanding of the problem of stress concentrations in composites. This book is the first to address the problem of laminated composites containing stress concentrations in a systematic way.

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

Book Description
The field of structural optimization is still a relatively new field undergoing rapid changes in methods and focus. Until recently there was a severe imbalance between the enormous amount of literature on the subject, and the paucity of applications to practical design problems. This imbalance is being gradually redressed now. There is still no shortage of new publications, but there are also exciting applications of the methods of structural optimizations in the automotive, aerospace, civil engineering, machine design and other engineering fields. As a result of the growing pace of applications, research into structural optimization methods is increasingly driven by real-life problems. Most engineers who design structures employ complex general-purpose software packages for structural analysis. Often they do not have any access to the source the details of program, and even more frequently they have only scant knowledge of the structural analysis algorithms used in this software packages. Therefore the major challenge faced by researchers in structural optimization is to develop methods that are suitable for use with such software packages. Another major challenge is the high computational cost associated with the analysis of many complex real-life problems. In many cases the engineer who has the task of designing a structure cannot afford to analyze it more than a handful of times.

Book Description
The International Union of Theoretical and Applied Mechanics (IUTAM) initiated and sponsored an International Symposium on Optimization of Mechanical Systems held in 1995 in Stuttgart, Germany. The Symposium was intended to bring together scientists working in different fields of optimization to exchange ideas and to discuss new trends with special emphasis on multi body systems. A Scientific Committee was appointed by the Bureau of IUTAM with the following members: S. Arimoto (Japan) EL. Chernousko (Russia) M. Geradin (Belgium) E.J. Haug (U.S.A.) C.A.M. Soares (Portugal) N. Olhoff (Denmark) W.O. Schiehlen (Germany, Chairman) K. Schittkowski (Germany) R.S. Sharp (U.K.) W. Stadler (U.S.A.) H.-B. Zhao (China) This committee selected the participants to be invited and the papers to be presented at the Symposium. As a result of this procedure, 90 active scientific participants from 20 countries followed the invitation, and 49 papers were presented in lecture and poster sessions.

Book Description
The papers contained herein were presented at the Third International Conference on Composite Structures (ICCS/3) held at Paisley College of Technology, Paisley, Scotland, in September 1985. 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 USAF European Office of Aerospace Research and Development, and the US Army Research, Development and Standard isation Group-UK. It forms a natural and ongoing progression from the highly successful First and Second International Conferences on Composite Structures (ICCS/l and ICCS/2) held at Paisley in 1981 and 1983, respectively. To label composites as rather specialised, sophisticated, space-age structural materials would be to underestimate greatly their wider industrial potential. It is unquestionably true that they will play an increasingly dominant, if not decisive, role in aerospace engineering. Indeed a future aircraft industry without composites as the prime structural materials is inconceivable. However, in an energy-conscious world the high specific weights and stiffnesses of composites make them an attractive proposition in every sphere of transportation engineering. This fact is soundly underlined in one of the Plenary papers contained herein and in one of the sessions devoted to this subject. I t would also be a considerable mistake to interpret composites as simply lightweight alternatives to conventional metallic structural materials.
