Recent Milestone and Technology Development in Sustainable Energy and Advanced Material for Applied Engineering and Industry
This research applies a numerical study of topology optimization of laminate composite structures by using a Finite Element Method. In this methodology, the plies orientation is excluded from the optimization. The geometry-based optimization from frames of a MALE UAV fuselage structure is presented. The minimum strain energy with an optimization constraint of 20 percent of weight reduction is used in the objective function. Before the primary analysis, benchmark studies of topology optimization without considering orientations from previously published literature are performed. The convergence studies were taken to acquire the appropriate mesh size in the FEM technique, which utilized a four-noded shell element. The FE analysis and optimization results showed that the structural design of the newly frame composite fuselage MALE UAV meets the structural strength requirements specified in the airworthiness standard STANAG 4671.
Teknologi Hijau Bidang Perkapalan, Upaya Menuju Zero Carbon 2050 (Green Technology For Ship)
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.
Structural and Failure Mechanics of Sandwich Composites
"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...
An Introduction to the Mechanical Properties of Solid Polymers
Provides a comprehensive introduction to the mechanical behaviour of solid polymers. Extensively revised and updated throughout, the second edition now includes new material on mechanical relaxations and anisotropy, composites modelling, non-linear viscoelasticity, yield behaviour and fracture of tough polymers. The accessible approach of the book has been retained with each chapter designed to be self contained and the theory and applications of the subject carefully introduced where appropriate. The latest developments in the field are included alongside worked examples, mathematical appendices and an extensive reference. Fully revised and updated throughout to include all the latest developments in the field Worked examples at the end of the chapter An invaluable resource for students of materials science, chemistry, physics or engineering studying polymer science
Handbook of Plastics Recycling
This book discusses some of the state-of-the-art techniques of recycling post-consumer plastic materials and focuses on mechanical recycling, chemical recycling and energy recovery. The book is intended for all those who are interested in recycling of post consumer plastic waste. Although, this book discusses technical aspects of recycling, the authors have endeavoured to make this book easily understandable to anyone interested in the subject enabling the reader to gain a thorough grounding in all the subjects discussed.
Pachinko
* The million-copy bestseller* * National Book Award finalist * * An instant New York Times Bestseller and one of their 10 Best Books of 2017 * * Selected for Emma Watson's Our Shared Shelf book club * 'This is a captivating book... Min Jin Lee's novel takes us through four generations and each character's search for identity and success. It's a powerful story about resilience and compassion' BARACK OBAMA. Yeongdo, Korea, 1911. Teenaged Sunja, the adored daughter of a fisherman, falls for a wealthy yakuza. He promises her the world, but when she discovers she is pregnant – and that her lover is married – she refuses to be bought. Facing ruin, she accepts an offer of marriage from a gentle minister passing through on his way to Japan. Following a man she barely knows to a hostile country where she has no friends, Sunja will be forced to make some difficult choices. Her decisions will echo through the decades. Spanning nearly 100 years of history, Pachinko is an unforgettable story of love, sacrifice, ambition and loyalty told through four generations of one family.

Polyurethane Elastomers
A comprehensive account of the physical / mechanical behaviour of polyurethanes (PU ́s) elastomers, films and blends of variable crystallinity. Aspects covered include the elasticity and inelasticity of amorphous to crystalline PUs, in relation to their sensitivity to chemical and physical structure. A study is made of how aspects of the constitutive responses of PUs vary with composition: the polyaddition procedure, the hard segment, soft segment and chain extender (diols and diamines) are varied systematically in a large number of systems of model and novel crosslinked andthermoplastic PUs. Results will be related to: microstructural changes, on the basis of evidence from x-ray scattering...
