Composite Materials in Maritime Structures, Volume 2 (Cambridge Ocean Technology Series (No. 5))

321 Pages·2008·19.573 MB·English

by  R. Ajit Shenoi (editor), John F. Wellicome (editor)

The two volumes that comprise this work provide a
comprehensive guide and source book on the marine use of
composite materials.
The first volume. Fundamental Aspects, provides a rigorous
development of theory. Areas covered include materials science,
environmental aspects, production technology, structural
analysis, finite-element methods, materials failure mechanisms
and the role of standard test procedures. An appendix gives
tables of the mechanical properties of common polymeric
composites and laminates in marine use.
The second volume, Practical Considerations, examines how
the theory can be used in the design and construction of marine
structures, including ships, boats, offshore structures and other
deep-ocean installations. Areas covered in this second volume
include design, the role of adhesives, fabrication techniques, and
operational aspects such as response to slam loads and fatigue
performance. The final three chapters of the book cover
regulatory aspects of design, quality and safety assessment, and
management and organisation.
These volumes will provide an up-to-date introduction to this
important and fast-growing area for students and researchers in
naval architecture and maritime engineering. It will also be of
value to practising engineers as a comprehensive reference book.
