Get Finite Elemente in der Baustatik. Band 1: Lineare Statik der PDF

By Werkle H.

Die Methode der Finiten Elemente ist heute ein Standardverfahren zur Berechnung von Flächentragwerken im konstruktiven Ingenieurbau mit Hilfe des pcs. In diesem Buch werden die theoretischen Grundlagen der Methode für Stab-, Platten- und Scheibentragwerke dargestellt, soweit sie für das Verständnis des Verfahrens und eine qualifizierte Anwendung erforderlich sind. Hierbei werden auch die wichtigsten, in kommerzielle Finite-Element-Software implementierten Elementtypen und deren Eigenschaften untersucht. Darüber hinaus werden Fragen der Modellbildung ausführlich behandelt und Hinweise zur Interpretation der Ergebnisse gegeben. Anhand einer Reihe von Beispielen werden wesentliche Aussagen verdeutlicht. Das Buch richtet sich an praktisch tätige Ingenieure sowie an Studierende der Fachhochschulen und - soweit die Anwendung der Finite-Elemente-Methode im Vordergrund steht - auch der Technischen Hochschulen. Es hat zum Ziel, zu einem vertieften Verständnis der Finite-Elemente-Methode und der qualifizierten Interpretation der mit ihr erhaltenen Ergebnisse in der Praxis beizutragen.

Read e-book online Numerical Methods for Bifurcations of Dynamical Equilibria PDF

By Willy J. F. Govaerts

ISBN-10: 0898714427

ISBN-13: 9780898714425

Dynamical platforms come up in all fields of utilized arithmetic. the writer makes a speciality of the outline of numerical equipment for the detection, computation, and continuation of equilibria and bifurcation issues of equilibria of dynamical platforms. This subfield has the actual charm of getting hyperlinks with the geometric thought of differential equations, numerical research, and linear algebra.

Several positive aspects make this ebook specified. the 1st is the systematic use of bordered matrix equipment within the numerical computation and continuation of assorted bifurcations. the second one is an in depth therapy of bialternate matrix items and their Jordan constitution. Govaerts discusses their use within the numerical tools for Hopf and comparable bifurcations. a 3rd function is a unified therapy of singularity concept, with and with out a extraordinary bifurcation parameter, from a numerical standpoint. ultimately, numerical equipment for symmetry-breaking bifurcations are mentioned intimately, as much as the elemental circumstances lined through the equivariant branching lemma.

Theorie und Numerik einer dreidimensionalen by Bischoff M. PDF

By Bischoff M.

Ausgangspunkt der Arbeit ist ein 7-Parameter-Schalenmodell mitBeruecksichtigung der Dickenaenderung, das von Buechter und Ramm (1992) vorgestelltwurde. Die Anwendung eines solchen 3D-Schalenmodells ist insbesondere dann sinnvoll,wenn vollstaendig dreidimensionale Stoffgesetze verwendet werden sollen, womit auchProbleme mit grossen Verzerrungen berechnet werden koennen.Im Gegensatz zu Buechter und Ramm (1992) wird das Schalenmodell in dieser Arbeit unabhaengig von der FE-Formulierung als Semidiskretisierung des Schalenkontinuums inDickenrichtung auf der foundation eines Mehrfeldfunktionals hergeleitet. So kann das7-Parameter-Modell als zweidimensionale, kontinuierliche Theorie mit sieben kinematischenFreiheitsgraden professional materiellem Punkt der Schalenmittelflaeche verstanden werden.Es wird angestrebt eine physikalische Interpretation der kinematischen und statischen Variablen zu geben. Der Schwerpunkt liegt dabei auf den Groessen, die beikonventionellen 5-Parameter-Formulierungen nicht auftreten. Fuer den linearen Anteilder Querschubverzerrungen wird ein neuer Schubkorrekturfaktor vorgeschlagen, der denFehler bezueglich der vollstaendig dreidimensionalen Loesung vermindern kann. Es wirdausserdem gezeigt, dass die Anzahl der kinematischen und statischen Variablen in diesem7-Parameter-Modell im Hinblick auf die Verwendung dreidimensionaler Stoffgesetze`optimal' ist.Schliesslich wird ein einheitliches Konzept zur Formulierung drei- und viereckigerSchalenelemente mit Ansaetzen beliebigen Polynomgrades vorgestellt. Dabeiwerden aus der Literatur bekannte Methoden mit eigenen Entwicklungen kombiniert.Ausserdem wird eine Verbesserung bei der Behandlung von Schalen mit Knickenvorgeschlagen. Das Konzept wird fuer lineare und quadratischeDrei- und Viereckelemente verwirklicht. In numerischen Berechnungen linearer sowie materiell und geometrisch nichtlinearer Probleme werden die Eigenschaften der vorgestellten Elemente untersucht.
