Hierbei werden sowohl die Klassische Laminattheorie als auch Laminattheorien höherer Ordnung diskutiert, und als ein Spezialfall wird die sog. Sandwichbauweise angesprochen. Der fünfte und letzte Abschnitt dieses Buchs ist den Schalen, also gekrümmten Flächentragwerken gewidmet, wobei hier der gängigen Einteilung in die Membrantheorie einerseits und der Biegetheorie andererseits gefolgt wird.Dieses Buch richtet sich an Studierende an Fachhochschulen und Universitäten, aber auch an Ingenieurinnen und Ingenieure in der Praxis sowie an Forscherinnen und Forscher der Ingenieurwissenschaften.

Flächenverbrauch in der Metropolregion Rheinland 1975–2030: Regionaler Landnutzungswandel im Kontext von Klimaanpassung (essentials)

by Andreas Rienow Frank Thonfeld Anke Valentin

Die Autoren schaffen mit der Entwicklung kleinräumiger Lösungen zum Umgang mit dem Landnutzungs- und Klimawandel Verständnis und Bewusstsein beim Leser und bieten auf diese Weise eine gute Basis für politisches Handeln. Sie zeigen, dass zunächst die Bauleitplanung in der Pflicht ist, wie es in vielen lokalen Klimaanpassungskonzepten nachzuvollziehen ist. Aber auch die Zivilbevölkerung kann ihren Beitrag zu einer klimaangepassten Gestaltung unserer Umwelt leisten. Politik und Verwaltung können Vorgaben für neu geplante Gebäude geben, die sich an den Erkenntnissen orientieren, die über Fernerkundungsdaten und Klimamodelle erzielt werden. Gerade die nach außen orientierte Siedlungsentwicklung der letzten Jahrzehnte wird über den Blick auf die klassifizierten Satellitenbilder erschreckend gut sichtbar.

Flame Hardening (Werkstattbücher)

by Hans Wilhelm Grönegress

This book intended for shop use tries to familiarize the reader with the peculiari­ ties of a hardening method which due to its many advantages is now in use,many shops. A general knowledge of the principles of hardening and heat treating is presumed. Introduction 1. The name of the process. Flame hardening is a method derived from the old quench hardening and is used for the surface hardening of heat treatable steels. Flame hardening is so named in analogy to flame cutting as the use of a flame is a distinctive feature of this process as opposed to the use of a furnace. 2. Characteristics of flame hardening. In flame hardening the area to be 6 hardened is heated with a burner of large heat capacity (approx. 0.5 · 10 kcaljhr/ meter of flame lengths or 50,000 BTUfhr/inch of flame length) supplied with a mixture of fuel gas and oxygen. The hardening temperature is thus reached in so short a time at the surface that a heat jam is created, that is, more heat is supplied to the surface than can be dissipated to the interior of the workpiece. As the querr­ ehing takes place immediately after the heating the penetration of the heat to greater depth is prevented and only the outer layer subject to wear is hardened. The core of the workpiece remains unaffected by this heat treatment in cantrast to the other hardening methods where the entire piece is through heated in a furnace.

Flame-Retardant Polymeric Materials: Volume 2

by Menachem Lewin

Flammability has been recognized as an increasingly important social and scientific problem. Fire statistics in the United States (Report of the National Commission on Fire Prevention and Control, "America Burning," 1973) emphasized the vast devastation to life and property--12,OOO lives lost annually due to fire, and these deaths are usually caused by inhaling smoke or toxic gases; 300,000 fire injuries; 11.4 billion dollars in fire cost at which 2.7 billion dollars is related to property loss; a billion dollars to burn injury treatment; and 3.3 billion dollars in productivity loss. It is obvious that much human and economic misery can be attributed to fire situations. In relation to this, polymer flammability has been recognized as an in­ creasingly important social and scientific problem. The development of flame-retardant polymeric materials is a current example where the initia­ tive for major scientific and technological developments is motivated by sociological pressure and legislation. This is part of the important trend toward a safer environment and sets a pattern for future example. Flame retardancy deals with our basic everyday life situations-housing, work areas, transportation, clothing and so forth-the "macroenvironment" capsule within which "homosapiens" live. As a result, flame-retardant polymers are now emerging as a specific class of materials leading to new and diversified scientific and technological ventures.

Flammability of Cartoned Lithium Ion Batteries (SpringerBriefs in Fire)

by R. Thomas Long Jr. Jason A. Sutula Michael J. Kahn

This SpringerBrief summarizes a full-scale, reduced commodity fire testing comparison of cartoned Lithium ion batteries and FM Global standard commodities in a rack storage configuration, as reported by FM Global. Tests evaluate the flammability characteristics of the materials and the effectiveness of ceiling level only sprinkler protection. The testing methods, discussed in depth, are scaled down from standard commodity classification testing due to the inordinate costs of Li-ion batteries. Small format Li-ion battery commodities represent both commercially available battery formats and Li-ion battery containing devices. The selected Li-ion battery types are individual 18650 format cylindrical cells, power tool packs comprised of 18650 format cells and polymer cells. The selected comparison commodities are the FM Global standard Class 2 and Cartoned Unexpanded Plastic (CUP). The results offer insight into the combined effects of different storage heights, ceiling height, protection system design, battery density, state of charge and battery type. Flammability of Cartoned Lithium Ion Batteries is intended for practitioners as a tool for analyzing commodity testing methods and providing data about potential hazards. Researchers working in a related field will also find the book valuable.

Flash Floods: Forecasting and Warning

by Kevin Sene

Flash floods typically develop in a period a few hours or less and can arise from heavy rainfall and other causes, such as dam or flood defence breaches, and ice jam breaks. The rapid development, often associated with a high debris content, can present a considerable risk to people and property. This book describes recent developments in techniques for monitoring and forecasting the development of flash floods, and providing flood warnings. Topics which are discussed include rainfall and river monitoring, nowcasting, Numerical Weather Prediction, rainfall-runoff modelling, and approaches to the dissemination of flood warnings and provision of an emergency response.The book is potentially useful on civil engineering, water resources, meteorology and hydrology courses (and for post graduate studies) but is primarily intended as a review of the topic for a wider audience.
