October 2013 www.sname.org/sname/mt (in review) Adhesives in Marine Engineering By Jan R. Weitzenböck PUBLISHED BY WOODHEAD PUBLISHING REVIEWED BY ALBERT W. HORSMON JR. This is not your simple [name a manufac- turer] guide to adhesives.? There are no direct tables of what to use for which appli- cation, and the book is not related to just marine engineering. A more appropriate title may have been applications and design of adhesives in the marine environment.? What you will discover is a number of in-depth recommended analy- sis schemes by which to evaluate and choose an adhesive system. Woodhead Publishing developed this series of books by choosing a lead author with expert knowledge of the subject (Jan Weitzenböck is an applications engineer for Det Norske Veritas), who could then select a number of other subject matter experts who address various aspects of the subject. e book is arranged as follows. Introduction. General considerations and suggestions for oversight organization approval. Selecting adhesives for the marine environment and pre- design. is is mostly an engineering design methodology primer. Designing adhesively bonded joints for ship applications. Although mostly written from the United Kingdoms Royal National Lifeboat Institution viewpoint on composite applica- tions, this chapter shows some extremes to which adhesives are exposed, and raises additional design considerations. Designing adhesive joints for wind turbines. At first blush, one might wonder if this subject belongs in a book about marine engineering, but it concentrates on fatigue consider- ations, providing an interesting evaluation of stress-strain curves and load sequencing. It includes examples of fatigue testing for adhesives. Predicting the failure of bonded structural joints. is chap- ter covers the detail design of dierent types of joints. e reader is warned against thinking that typical engineering analyses can be applied to the often-stretchy adhesives bonded to stier, usually stronger, substrates. Non-linear and fracture mechanics analysis methods are proposed to address these issues. Testing. is covers a number of necessarily specialized testing methods for determining tensile strength, lap shear strength, peel strength, thermal performance, and other aspects of adhesives. Moisture resistance. Most adhesives will absorb moisture at some rate, so designing around or taking into consideration adhesive performance in moisture is necessary. Good practi- cal and technical advice is given, including various means by which to test for moisture resistance. Durability in wet conditions. is expands on the previous chapter and addresses the eects of the marine environment. e method of using the dierent authors becomes a bit tedious, as each is obliged to give his own introduction, but the overall eect is that the subject matter is well covered. Each chapter is extensively referenced and sources for further read- ing are generously provided. While the book is certainly not an adhesives processing guide, and will not take the reader through joint preparation, mixing, application, and curing, it is recommended as a rst reference for anyone planning serious adhesive applications in the marine environment.

One of the fun aspects of mathematical modeling is the ability to sail? the yacht virtually, using the authors PC-Sail velocity prediction program. As one reads Mr. Martins book, one senses that he has enjoyed developing many dierent craft and competing? them numerically. is is not a book about the crafting of museum-quality dis- play models, nor is it a text on yacht design. While PC-Lines and PC-Sail appear to be excellent pieces of software with great usefulness, they do not represent a development package ready for use in a production shop. Instead, I suggest that this is an excellent book for amateurs and students. In my own work as an educator, I have been wondering if I could use this book in an undergraduate or even junior-college setting to intro- duce students to the STEM disciplines in naval architecture. A course based on this approach might combine elements of wood shop and math class, by starting with the building of a physical model, and then representing that hull as a mathe- matical model. e ship could then be improved by evolving her through the PC-Sail VPP, and then perhaps by again build- ing a physical model of the nal revised design and sailing it against its progenitor. e author, David E. Martin, has an interesting background that underscores this serious hobbyist approach to yacht mod- eling. He holds a masters degree in theoretical and applied mechanics from the University of Illinois, and on that basis worked as the director of auto safety engineering for General Motors until 1987. After retirement from General Motors, Martin enrolled in the naval architecture program at the University of Michigan and completed a bachelor of science in naval archi- tecture. He came to Michigan to become a better hobbyist and naval historian, and his interests have clearly inuenced the architecture of this book. I nd this book quite interesting. It slices through the subject matter on a course that is in some sense perpendicular to the normal treatment, thus my statement that it is hard to know where to shelve it in my library. But shelve it I shall, and I shall often reach for it both for my own enjoy- ment and so that my students can use it to get a dierent insight into our topics. To quote from the authors introduction: Good modeling, good learning, good sailing! ey are all fun.? MT Chris B.
