Introduction to Plastics Engineering (eBook, ePUB)

• Format: ePub

Produktbeschreibung

The authoritative introduction to all aspects of plastics engineering -- offering both academic and industry perspectives in one complete volume. Introduction to Plastics Engineering provides a self-contained introduction to plastics engineering. A unique synergistic approach explores all aspects of material use -- concepts, mechanics, materials, part design, part fabrication, and assembly -- required for converting plastic materials, mainly in the form of small pellets, into useful products. Thermoplastics, thermosets, elastomers, and advanced composites, the four disparate application areas of polymers normally treated as separate subjects, are covered together. Divided into five parts -- Concepts, Mechanics, Materials, Part Processing and Assembly, and Material Systems -- this inclusive volume enables readers to gain a well-rounded, foundational knowledge of plastics engineering. Chapters cover topics including the structure of polymers, how concepts from polymer physics explain the macro behavior of plastics, evolving concepts for plastics use, simple mechanics principles and their role in plastics engineering, models for the behavior of solids and fluids, and the mechanisms underlying the stiffening of plastics by embedded fibers. Drawing from his over fifty years in both academia and industry, Author Vijay Stokes uses the synergy between fundamentals and applications to provide a more meaningful introduction to plastics. * Examines every facet of plastics engineering from materials and fabrication methods to advanced composites * Provides accurate, up-to-date information for students and engineers both new to plastics and highly experienced with them * Offers a practical guide to large number of materials and their applications * Addresses current issues for mechanical design, part performance, and part fabrication Introduction to Plastics Engineering is an ideal text for practicing engineers, researchers, and students in mechanical and plastics engineering and related industries.

Rezensionen

Although Author Dr. Vijay Stokes humbly includes "introduction" in the book title, the treatment in this book is quite extensive and inclusive, with 25 chapters and over 1000 pages. This volume essentially contains every facet of plastics engineering from materials and fabrication methods to advanced composites. It endorses a unique synergistic approach to implementing the ideas of mechanistic principles and polymer physics to practical applications of polymers and composites. Engineers are natural readers of this book. In this book, concepts from polymer physics explain the macro behavior of plastics, including deformation, flow and rheology, which are of vital importance in design and fabrication with plastics. Engineers would therefore learn the new tool sets to tailor plastics in various engineering applications. Materials scientists who have an interest in applications of polymers would greatly benefit from this book as well. The book also contains detailed derivations and design analysis and may be used as a textbook for college seniors or students at an introductory graduate level. --Professor Donggang Yao, Journal of Manufacturing Science and Engineering

The book, Introduction of Plastics Engineering, is a great resource both for students beginning to learn about plastics, and for practicing engineers trying to clarify concepts unique to polymers. The author writes that he started working on plastics in mid career;the learning process he went through is reflected in how he has organized the material in the over 1000 pages in this book. It works. As a reviewer who has worked with polymers for almost four decades, I give this book high marks-- Professor Tim A. Osswald, International Polymer Processing

Overall, this is an important addition to the plastics engineering series available in the market. While most books on plastics engineering emphasize materials' aspects and most design books are based on mechanical engineering concepts, this book uses mechanics based engineering principles to understand plastics engineering. Hence, the book covers the existing gap. The principles are discussed with basic knowledge of mathematics and easy to follow.--Professor Anil K. Bhowmick, AIChE Journal
