Ebene Flächentragwerke: Grundlagen der Modellierung und - download pdf or read online

By Holm Altenbach,Johannes Altenbach,Konstantin Naumenko

Das intestine eingeführte Werk Ebene Flächentragwerke erscheint nun in der 2. Auflage. Ausgehend von einer Klassifikation der Modelle ebener Flächentragwerke und den Grundgleichungen der linearen Elastizitätstheorie werden zunächst systematisch die Gleichungen für isotrope Scheiben und Platten abgeleitet. Dabei wird ein didaktisch einheitliches Konzept eingesetzt. Die Gleichungen werden in kartesischen Koordinaten, Polarkoordinaten und schiefwinkligen Koordinaten formuliert. In Ergänzung der ersten Auflage wird auch eine Plattentheorie in koordinatenfreier Schreibweise behandelt, so dass der Leser einen leichteren Zugang zu modernen Konzepten der Formulierung von Flächentragwerkstheorien erhält. Die Diskussion der Plattenmodelle nach Kirchhoff, Mindlin und von Kármán zeigt die Möglichkeiten und Grenzen dieser Strukturmodelle.Für schubstarre und schubelastische Platten mit kleinen Durchbiegungen wird auch anisotropes Materialverhalten einbezogen, und es werden die Strukturgleichungen der klassischen Laminattheorie und der Schubdeformationstheorie erster Ordnung angegeben. Es folgt ein kurzer Einblick in Theorien zur examine dreischichtiger Platten. Die Berücksichtigung vorgegebener Temperaturfelder erfolgt für alle Plattenmodelle im Rahmen der entkoppelten Thermoelastizität.Der Leser erhält einen umfassenden Überblick über die Anwendung bedeutsamer Strukturmodelle ebener Flächentragwerke. Die nach Aufgabenklassen geordneten zahlreichen Beispiele können als Referenzlösungen zur Testung numerischer Verfahren genutzt werden. Die Aufnahme der sogenannten Reduktionsverfahren von Wlassow und Kantorowitsch soll ihre Leistungsfähigkeit für die Ableitung einfacher und analytischer Näherungslösungen durch die Reduktion der Strukturgleichungen auf eindimensionale Formulierungen verdeutlichen.

Download e-book for kindle: Einführung in die Technische Mechanik: Statik by Herbert Balke

By Herbert Balke

Das Lehrbuch schafft einen ersten Zugang zu den Grundgesetzen der Mechanik. Gestützt auf dem Begriff des starren Körpers und der unabhängig eingeführten Lasten Kraft und second werden die beiden eigenständigen Bilanzen der Kräfte und Momente im Fall des Gleichgewichts eines Körpers und beliebiger Teile desselben postuliert. Diese hauptsächlich von Euler vorgenommene Ergänzung der Newtonschen Mechanik eröffnet einen Weg, der die weiterführenden Teile Festigkeitslehre und Kinetik mit der Statik in einem einheitlichen Konzept verbindet. Damit werden günstige Voraussetzungen für ein erleichtertes Verständnis der gesamten Technischen Mechanik und anschließender, insbesondere der Computermechanik zugrunde liegender Gebiete geschaffen. Das Buch behandelt in bewährter Anordnung ebene einfache und zusammengesetzte Tragwerke einschließlich der Schnittreaktionen sowie in geringerem Umfang auch räumliche Tragwerke. Reibungsphänomene werden beschrieben. Das Buch schließt mit den Berechnungsmethoden für den Schwerpunkt und die Flächenmomente zweiter Ordnung, welche in der Festigkeitslehre benötigt werden. Die knappe Darstellung lehnt sich stark an den Inhalt verschiedener Kursvorlesungen an. Die mathematischen Hilfsmittel werden so gering wie möglich gehalten. Zahlreiche Aufgaben mit vollständig durchgerechneten Lösungen unterstützen die Erarbeitung des Stoffs. Daher ist das Buch neben der Vorlesung auch zum Selbststudium bestens geeignet.

Uncertainty Assessment of Large Finite Element Systems: 24 by Christian A. Schenk,Gerhart I. Schuëller PDF

By Christian A. Schenk,Gerhart I. Schuëller

The remedy of uncertainties within the research of engineering constructions continues to be one of many top class demanding situations in sleek structural mechanics. it's only lately that the advancements in stochastic and deterministic computational mechanics started to be synchronized. To foster those advancements, novel computational strategies for the uncertainty evaluate of huge finite point structures are provided during this monograph. The stochastic enter is modeled through the so-called Karhunen-Loève growth, that's formulated during this context either for scalar and vector stochastic strategies in addition to for random fields. fairly for strongly non-linear buildings and structures the direct Monte Carlo simulation strategy has confirmed to be most effective as approach to answer. The services of the built methods are established via displaying a few functional applications.

Irreversible Phenomena: Ignitions, Combustion and Detonation - download pdf or read online

By Kunio Terao

beliefs are basic and ready to be simply understood, yet by no means exist in truth. during this publication a conception in response to the second one legislations of thermodynamics and its functions are defined. In thermodynamics there's a thought of a terrific fuel which satisfies a mathematical formulation PV = RT. This formulation can appro- mately be utilized to the genuine gasoline, as far as the fuel has no longer a particularly excessive strain and occasional temperature. In reference to the second one legislations of thermo- namics there's additionally an idea of reversible and irreversible strategies. The reversible technique is a phenomenon continuing at an infinitely low pace, whereas the irreversible strategy is that continuing with a finite pace. this kind of procedure with an infinitely sluggish pace can fairly by no means ensue, and all procedures saw are regularly irreversible, for this reason, the reversible technique is a perfect strategy, whereas the irreversible approach is a true procedure. based on the 1st legislation of thermodynamics the power raise dU of the thermodynamic process is a sum of the warmth dQ extra to the procedure and paintings dW performed within the procedure. virtually, even if, the mathematical formulation of the legislation is frequently expressed via the equation , or a few comparable equations derived from this formulation, is utilized to many phenomena. Such formulae are, even though, th- retically basically acceptable to phenomena continuing at an infinitely low speed, that's, reversible methods or excellent processes.
