Available in PDF, EPUB and Kindle. Book excerpt: UHMWPE Biomaterials Handbook describes the science, development, properties and application of of ultra-high molecular weight polyethylene (UHMWPE) used in artificial joints. This material is currently used in 1.4 million patients around the world every year for use in the hip, knee, upper extremities, and spine. Since the publication of the 1st edition there have been major advances in the development and clinical adoption of highly crosslinked UHMWPE for hip and knee replacement. There has also been a major international effort to introduce Vitamin E stabilized UHMWPE for patients. The accumulated knowledge on these two classes of materials are a key feature of the 2nd edition, along with an additional 19 additional chapters providing coverage of the key engineering aspects (biomechanical and materials science) and clinical/biological performance of UHMWPE, providing a more complete reference for industrial and academic materials specialists, and for surgeons and clinicians who require an understanding of the biomaterials properties of UHMWPE to work successfully on patient applications. The UHMWPE Handbook is the comprehensive reference for professionals, researchers, and clinicians working with biomaterials technologies for joint replacement New to this edition: 19 new chapters keep readers up to date with this fast moving topic, including a new section on UHMWPE biomaterials; highly crosslinked UHMWPE for hip and knee replacement; Vitamin E stabilized UHMWPE for patients; clinical performance, tribology an biologic interaction of UHMWPE State-of-the-art coverage of UHMWPE technology, orthopedic applications, biomaterial characterisation and engineering aspects from recognised leaders in the field

This book was released on 2013-04-17 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents a continuation of the Polymer Science and Technology series edited by Dr. D. M. Brewis and Professor D. Briggs. The theme of the series is the production of a number of stand alone volumes on various areas of polymer science and technology. Each volume contains short articles by a variety of expert contributors outlining a particular topic and these articles are extensively cross referenced. References to related topics included in the volume are indicated by bold text in the articles, the bold text being the title of the relevant article. At the end of each article there is a list of bibliographic references where interested readers can obtain further detailed information on the subject of the article. This volume was produced at the invitation of Derek Brewis who asked me to edit a text which concentrated on the mechanical properties of polymers. There are already many excellent books on the mechanical properties of polymers, and a somewhat lesser number of volumes dealing with methods of carrying out mechanical tests on polymers. Some of these books are listed in Appendix 1. In this volume I have attempted to cover basic mechanical properties and test methods as well as the theory of polymer mechanical deformation and hope that the reader will find the approach useful.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to give readers a basic understanding of commonly used additive manufacturing techniques as well as the tools to fully utilise the strengths of additive manufacturing through the modelling and design phase all the way through to post processing. Guidelines for 3D-printed biomedical implants are also provided. Current biomedical applications of 3D printing are discussed, including indirect applications in the rapid manufacture of prototype tooling and direct applications in the orthopaedics, cardiovascular, drug delivery, ear-nose-throat, and tissue engineering fields. Polymer-Based Additive Manufacturing: Biomedical Applications is an ideal resource for students, researchers, and those working in industry seeking to better understand the medical applications of additive manufacturing.

This book was released on 2021 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lightweight and robust materials are of interest for many applications. Ultra-high molecular weight polyethylene (UHMWPE) fibers are currently capable of tensile properties comparable to common industrial materials while also providing a low density. A few manufacturers have begun to utilize these materials in various applications, yet fundamental questions regarding the development and cause of the remarkable properties remain unanswered. In this study, the processing and structure of UHMWPE fibers from all stages of fabrication were analyzed to establish relationships with mechanical performance. The goal of this study was to determine which parameters were most critical in the development of the tensile response of the fiber, and then, if possible, how the processing could be altered to generate improved properties. A gel-spinning apparatus was developed to investigate the fiber spinning process. It was found that the strain rate during the spinning process, normalized by the relaxation time and represented via the Weissenberg number (Wi), correlates to the crystalline structure of the fiber, and that velocity ratio (the common method of characterization in these processes) is insufficient in classifying the structure of the spun fiber. A modified extensional rheometer was used to investigate the post drawing of the characterized fibers. Both draw temperature, draw velocity, and starting crystalline structure were studied. Draw velocity and temperature were found to control the sizes observed in the drawn structures. The initial morphology, when drawn at identical velocity and temperature, provides relatively constant structural sizes, but causes changes in the proportions of the structural features and the percent crystallinity. With this data set, we conclude that the crystalline structure is unrelated to mechanical performance. However the intermediate Wi fiber exhibits increased tensile strength and stiffness compared to the other spun fibers. This improved performance is attributed to differences in the initial crystallinity, or distribution of the different crystalline morphologies, of the samples. Differences in starting crystallinity are thought to alter the necessary amount of drawing required to reach the same mechanical response. While draw temperature and velocity do not directly improve the ultimate tensile properties, they do play a role in maximizing the possible deformation. Failure during drawing is observed to occur at a constant stress ceiling, which is independent of all observed parameters. This critical stress indicates a failure defect size of 0.93 nm through Griffith's Theory analysis. When maximum draw ratio is observed as a function of initial fiber diameter it is found that thinner fibers result in higher ultimate draw ratios. Controlling initial diameter, and to a lesser extent temperature and velocity, adjusts the strain at which this critical stress is reached providing higher draw ratios and ultimately higher crystallinity. Crystallinity is further found to be the ultimate determining factor in tensile property behavior, as seen through Fusion theory.
