Download E-books Approaches to the Description of Anisotropic Material Behaviour at Finite Elastic and Plastic Deformations. Theory and Numerics PDF

By Apel N.

The current paintings bargains with simply macroscopic descriptions of anisotropic fabric behaviour. Key points are new advancements within the thought and numerics of anisotropicplasticity. After a brief dialogue of the category of solids by means of symmetry ameliorations a survey approximately illustration idea of isotropic tensor services and tensor polynomials is given. subsequent substitute macroscopic ways to finite plasticity are mentioned. while contemplating a multiplicative decomposition of the deformation gradient into an elastic half and a plastic half, a 9 dimensional °ow rule is got that permits the modeling of plastic rotation. another technique bases at the creation of a metric-like inner variable, the so-called plastic metric, that bills for the plastic deformation of the cloth. during this context, a brand new category of constitutive types is received for the alternative of logarithmic lines and an additive decomposition of the full pressure degree into elastic and plastic components. The reputation of this classification of versions is because of their modular constitution in addition to the a+nity of the constitutive version and the algorithms contained in the logarithmic pressure house to versions from geometric linear thought. at the numerical facet, implicit and specific integration algorithms and pressure replace algorithms for anisotropic plasticity are constructed. Their numerical e+ciency crucially bases on their cautious development. specific concentration is wear algorithms which are appropriate for variational formulations. as a result of their (incremental) power estate, the corresponding algorithms will be formulated when it comes to symmetric amounts. a discounted garage eRort and not more required solver skill are key merits in comparison to their common opposite numbers.

Download E-books Theorie und Numerik einer dreidimensionalen Schalenformulierung 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.

Download E-books Computational electrophysiology: dynamical systems and bifurcations PDF

By Shinji Doi, Junko Inoue, Zhenxing Pan, Kunichika Tsumoto (auth.)

Biological structures inherently own a lot ambiguity or uncertainty. Computational electrophysiology is the single zone, from one of the giant and quickly becoming self-discipline of computational and structures biology, within which computational or mathematical types have succeeded. This booklet presents a realistic and speedy consultant to either computational electrophysiology and numerical bifurcation research. Bifurcation research is an important device for the research of such hugely nonlinear organic structures. Bifurcation conception offers how to study the impact of a parameter switch on a approach and to discover a serious parameter worth whilst the qualitative nature of the approach alterations. incorporated during this paintings are many examples of numerical computations of bifurcation research of varied types in addition to mathematical types with various abstraction degrees from neuroscience and electrophysiology. This quantity will profit graduate and undergraduate scholars in addition to researchers in varied fields of science.

By Erika Ábrahám, Andreas Grüner (auth.), Arnold Beckmann, Ulrich Berger, Benedikt Löwe, John V. Tucker (eds.)

CiE 2006: Logical techniques to Computational boundaries Swansea, Wales, June 30 - July five, 2006 Computability in Europe (CiE) is an off-the-cuff community of eu scientists engaged on computability concept, together with its foundations, technical devel- ment, and functions. one of the goals of the community is to boost our t- oretical realizing of what can and can't be computed, in any way of computation. Its scienti?c imaginative and prescient is extensive: computations should be played with discrete or non-stop information by means of all types of algorithms, courses, and - chines. Computations will be made by way of experimenting with any type of actual method obeying the legislation of a actual idea akin to Newtonian mechanics, quantum thought or relativity. Computations could be very common, based upon the principles of set idea; or very speci?c, utilizing the combinatorics of ?nite constructions. CiE additionally works on topics in detail relating to computation, specially theories of knowledge and data, and strategies for formal reasoning approximately computations. The resources of latest rules and techniques contain functional advancements in parts comparable to neural networks, quantum computation, ordinary computation, molecular computation, and computational studying. purposes are in all places, specially, in algebra, research and geometry, or information forms and programming. This quantity, Logical techniques to Computational limitations, is the proce- ings of the second one in a chain of meetings of CiE that used to be held on the Depa- ment of desktop technology, Swansea collage, 30 June - five July, 2006.
