Dr. Flavio Stochino, a Dresden Junior Fellow from the University of Sassari (Sardegna, Italy) is holding a lecture with the title “Modelling Brittle Fracture with an Eigenerosion Approach” on monday, 24.10.2016 from 13:00-13:30 at Georg-Schumann-Str. 7 – VMB / 106.
Abstract:
The eigenfracture scheme is capable of representing fracture development in brittle material. It is based on the concept of eigendeformations. They are used in mecha nics to describe deformations that cost no local energy.
Eigenerosion is derived from this approach by restricting the eigendeformations in a binary sense: they can be either zero, in which case the local behavior is elastic, or they can be equal to the local displacement gradient, in which case the correspon- ding material neighborhood is failed or eroded.
The application of this approach to finite element method yields to a simple and efficient element erosion criterion.
In this seminar the main characteristics of this method are presented along with some new ideas. A set of numerical examples will be also presented in order to assess its reliability and accuracy.
Am 28. und 29. April 2016 hat das Institut für Statik und Dynamik der Tragwerke eine Fachtagung unter dem Titel „Analysis and Characterization of Wooden Cultural Heritage by Scientific Engineering Methods“ am Händel-Haus in Halle durchgeführt. Die Veranstaltung fand in Zusammenarbeit mit dem Händel-Haus Halle, dem Institute for Building Materials (ETH Zürich) und dem Musée d’ethnographie de Genève statt, sie war Bestandteil eines von der Deutschen Forschungsgemeinschaft und dem Schweizer Nationalfonds geförderten Forschungsprojekts, das sich mit der experimentellen und numerischen Beschreibung vom Kulturgut aus Holz unter hygro-mechanischen Beanspruchungen widmet.
