Composites Design 1985

This report includes the fundamental equations for the stiffness and strength of laminated composites and two approaches to determine the optimum strength of laminates. Formulas for micromechanics and for unsymmetric laminates are simplified so that material and geometric factors can be more easily optimized than the unabridge theory. This report is intended as a source of information for designers, fabricators and researchers of composites. Originator supplied keywords include: Design; Optimum laminates; Thin wall construction; Simplified formulas.

Presenting a wealth of completely revised examples and new information, Introduction to Composite Materials Design, Second Edition greatly improves on the bestselling first edition. It incorporates state-of-the-art advances in knowledge and design methods that have taken place over the last 10 years, yet maintains the distinguishing features and vital content of the original. New material in this second edition: Introduces new background topics, including design for reliability and fracture mechanics Revises and updates information on polymer matrices, modern fibers (e.g., carbon nanotubes, Basalt, Vectran) and fiber forms such as textiles/fabrics Includes new information on Vacuum Assisted Resin Transfer Molding (VARTM) Incorporates major advances in prediction of unidirectional-lamina properties Reworks sections on material failure, including the most advanced prediction and design methodologies, such as in situ strength and Mohr-Coulomb criterion, etc. Covers all aspects of preliminary design, relegating finite element analysis to a separate textbook Discusses methodology used to perform damage mechanics analysis of laminated composites accounting for the main damage modes: longitudinal tension, longitudinal compression, transverse tension, in-plane shear, and transverse compression Presents in-depth analysis of composites reinforced with plain, twill, and satin weaves, as well as with random fiber reinforcements Expands the analysis of thin walled beams with newly developed examples and MATLAB® code Addresses external strengthening of reinforced-concrete beams, columns, and structural members subjected to both axial and bending loads The author distributes 78 fully developed examples throughout the book to illustrate the application of presented analysis techniques and design methodology, making this textbook ideally suited for self-study. Requiring no more than senior undergraduate-level understanding of math and mechanics, it remains an invaluable tool for students in the engineering disciplines, as well as for self-studying, practicing engineers.

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

Considered to have contributed greatly to the pre-sizing of composite structures, Composite Materials: Design and Applications is a popular reference book for designers of heavily loaded composite parts. Fully updated to mirror the exponential growth and development of composites, this English-language Third Edition: Contains all-new coverage of nanocomposites and biocomposites Reflects the latest manufacturing processes and applications in the aerospace, automotive, naval, wind turbine, and sporting goods industries Provides a design method to define composite multilayered plates under loading, along with all numerical information needed for implementation Proposes original study of composite beams of any section shapes and thick-laminated composite plates, leading to technical formulations that are not found in the literature Features numerous examples of the pre-sizing of composite parts, processed from industrial cases and reworked to highlight key information Includes test cases for the validation of computer software using finite elements Consisting of three main parts, plus a fourth on applications, Composite Materials: Design and Applications, Third Edition features a technical level that rises in difficulty as the text progresses, yet each part still can be explored independently. While the heart of the book, devoted to the methodical pre-design of structural parts, retains its original character, the contents have been significantly rewritten, restructured, and expanded to better illustrate the types of challenges encountered in modern engineering practice.

The third edition of Introduction to Composite Materials Design is a practical, design-oriented textbook aimed at students and practicing engineers learning analysis and design of composite materials and structures. Readers will find the third edition to be both highly streamlined for teaching, with new comprehensive examples and exercises emphasizing design, as well as complete with practical content relevant to current industry needs. Furthermore, the third edition is updated with the latest analysis techniques for the preliminary design of composite materials, including universal carpet plots, temperature dependent properties, and more. Significant additions provide the essential tools for mastering Design for Reliability as well as an expanded material property database.
