Download or read book Low density cellular plastics written by N.C. Hilyard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foams are gas filled integral structures in which the gas is finely dispersed throughout acontinuouslyconnected solid phase. The bulk density is usually substantially lower than that of the solid component, and for the foams which form the focus for this book the volume fraction of the gas phase is considerably greater than 0.5 and in most instances in excess of 0.9. Many ofthe materials encountered in every day experience, such as bread, plants and trees, structural materials for buildings, comfort materials for domestic and automotive seating, shock absorbers or car bumpers and materials for noise control, have one thing in common - the cellular nature of their physical structure. Whyare thesestructuressoimportantin the naturaland man-made world? The reasons are both technical and commercial. From a technical viewpoint cellular materials offer: 1. high specific stiffness and strength - making them suitable for structural applications; 2. closeto idealenergymanagement - hencetheir useinthermalandacoustic insulation, vibration damping, acoustic absorption and shock mitigation; and 3. comfort - hence their use for domestic and automotive seating.

Download or read book Patrick Tighe Architecture written by Patrick Tighe and published by Images Publishing. This book was released on 2016-08-20 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This beautifully designed and illustrated monograph sets out Patrick Tighe’s innovative, diverse and wide-ranging collection of contemporary work towards the post-digital, showing the reader a hyper- detailed analytical investigation of digital forms and their practices. It sets out how his architecture has brought a return to the real in an attempt to rethink the language and practice of architecture. The book’s many inspiring and intricate drawings render clear the ideas that show the palpable energy and momentum that exists in this practice. In every instance, this firm embraces dichotomy, mining its potential to produce a more vital and consequential architecture. The book’s stunning imagery and nuanced narratives tell the story of Tighe’s architecture across 35 projects spanning across the globe, to help establish how his work draws from and builds upon existing polarities to find resolution, and how tensions yield a more dynamic architecture. The work is multiple and varied: from the small-scale residential to the urban scale, from the United States to Europe to China to North Africa, from high-end villas for royalty to art installations to social housing projects. This compelling collection of work follows the following five key themes: CRAFT (from the manufactured to the technological); MATERIAL (from the natural to the synthetic); EXPERIENCE (from the actual to the perceptual); GEOMETRY (from the simple to the complex); and METHOD (from the analog to the digital). This distinguished monograph also includes an incisive introduction by Patrick Tighe and is augmented by two essays by Thom Mayne and Stephen Phillips, who also provide clarity and insightful discourse on how Tighe’s work is continuously in transition and evolving, and how he’s rethinking and engaging in a discourse to defamiliarize the familiar.

Download or read book Nonmetallic Materials and Composites at Low Temperature written by G. Hartwig and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This, the second special topical conference on the properties of Non-Metallic Materials at Low Temperatures, was sponsored by the International Cryogenic Materials Conference Board. The potential for plastics materials in the field of cryogenics is vast and as yet only partly explored. In addition, many other materials, which qualify for the title non-metallic but are not 'plastics', have numerous possible outlets in low temperature technology. This conference aimed at providing a forum, whereby specialists from Industry, the Universities and from Government sponsored Institutions could assemble to discuss the extent of our current knowledge. As it transpired, the meeting was also to high light the considerable gaps that still exist in our fundamental understanding of the low temperature behaviour of these materials. On this theme, during the course of the conference, a reference was made to an almost forgotten quotation by Lord Kelvin, who said: "When you cannot measure what you are speaking about, when you cannot express in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the stage of a science, whatever the matter be." This simple statement sums up the aims, objectives and hopefully the achievements of this conference. To discuss and disseminate the current knowledge on non-metallic materials in order that realistic predictions of in-service performance may be made.
