Material Sandwich adalah material yang terdiri dari lapisan kulit (facesheet) dan lapisan inti (core). Material sandwich ini ringan namun memiliki kekuatan yang lebih dalam menahan beban yang direncanakan. Kelebihan pada material ini sangat dibutuhkan dalam pembangunan infrastruktur sipil dan transportasi. Penelitian material sandwich beberapa tahun terakhir telah menjadi topik yang menarik untuk ditindak lebih lanjuti.
Adaptasi terhadap segala kondisi dan respon positif terhadap hal – hal yang terjadi sebagai bentuk dinamisasi industry menjadi syarat mutlat bagi kelangsungan sebuah sistem. Teknologi hijau bidang perkapalan merupakan suatu revolusi fundamental yang dilakukan sebagai upaya adaptasi terhadap perubahan tersebut. Buku ini mengupas tentang bagaimana konsep eco friendly vessel dan parameternya, bagaimana penerapan bahan bakar alternative dikapal dan tantangan masa depan pengembangannya, sistem operasional kapal dan pemanfaatan gas buang menjadi isu yang menarik untuk dibaca. Selain itu bagaimana efisiensi energi yang terkait dengan kelistrikan kapal, advanced propeller dan aplikasi teknologi dual fuel menjadi bagian chapter lain yang juga menarik untuk dibahas dan dipelajari lebih jauh. Teknologi hijau bidang perkapalan menjadi satu kajian yang menarik saat ini ditengah upaya menuju zero carbon 2050, mitigasi terhadap perubahan iklim dan pemanasan global yang menyebabkan banyak perubahan dalam kelangsungan kehidupan makhluk hidup.
The pressure on graduate students and new PhDs to publish their work continues to grow with writing and publishing considered an important measure of career success within the academy. There is, however, more to the process of getting published than those who are new to the process initially realize. The aim of this guide is to clarify the process and offer advice. Getting Published in Academic Journals is written for graduate students and newly graduated PhDs who want to publish their research in peer-reviewed academic journals. Getting Published in Academic Journals draws on the experiences of the authors as editors of peer-reviewed journals, as teachers of writing-for-publication courses and workshops, as researchers of the scholarly publication process, as reviewers of hundreds of articles, and as published authors. The book is written to be used in courses and workshops on publishing, as a supplement to the books in the revised and updated English in Today's Research World (Swales & Feak) series, and as a stand-alone guide for academic writers working independently.

FEM updating allows FEMs to be tuned better to reflect measured data. It can be conducted using two different statistical frameworks: the maximum likelihood approach and Bayesian approaches. This book applies both strategies to the field of structural mechanics, using vibration data. Computational intelligence techniques including: multi-layer perceptron neural networks; particle swarm and GA-based optimization methods; simulated annealing; response surface methods; and expectation maximization algorithms, are proposed to facilitate the updating process. Based on these methods, the most appropriate updated FEM is selected, a problem that traditional FEM updating has not addressed. This is found to incorporate engineering judgment into finite elements through the formulations of prior distributions. Case studies, demonstrating the principles test the viability of the approaches, and. by critically analysing the state of the art in FEM updating, this book identifies new research directions.
Analysis and Design of Structural Sandwich Panels serves as a simple guide to the fundamental aspects of the theory of sandwich construction and to the assumptions on which it is based. This book discusses the real importance of the assumptions made in sandwich theory concerning the relative stiffness and thickness of the faces and the core. Organized into 12 chapters, this book begins with an overview of the relatively simple problems of sandwich beams and struts. This text then discusses the bending of sandwich beams, which grows naturally from the ordinary theory of bending. Other chapters explore the bending and buckling of sandwich panels. This book discusses as well the panel analyses based on the Ritz method and on the derivation of differential equations for a sandwich plate. This book should be of interest not only to aeronautical engineers but also to readers concerned with the design of sandwich panels in the building, plastics, and boat-building industries.
The importance of small fishing craft to the world catch of fish cannot be underestimated but little attention has in the past been given to their design. The primary purpose of this book is to disseminate the specialized knowledge needed for designing improved small fishing vessels. It has been structured to cover every item which needs to be taken into account, working in easy stages from background material to the specification for a finished design. The logical and well–balanced format takes the reader through general principles to factors specific to fishing vessels and the content is so comprehensive that much will be of equal value to users and designers of larger vessels. It is an invaluable volume enhanced by detailed drawings of exceptional standard.
This important reference volume covers developments in all aspects of British library and information work during the five year period 2001-2005. The book provides a comprehensive record of library and information management during the past five years an
"Structural and Failure Mechanics of Sandwich Composites" by Leif A. Carlsson and George A. Kardomateas focuses on some important deformation and failure modes of sandwich panels such as global buckling, wrinkling and local instabilities, and face/core debonding. The book also provides the mechanics background necessary for understanding deformation and failure mechanisms in sandwich panels and the response of sandwich structural parts to a variety of loadings. Specifically, first-order and high-order sandwich panel theories, and three-dimensional elasticity solutions for the structural behavior outlined in some detail. Elasticity analysis can serve as a benchmark for judging the accuracy of...
