Special Issue on Computing with Polymorphic Uncertain Data


A Special Issue on Computing with Polymorphic Uncertain Data has been published in the International Journal of Reliability and Safety. The Special Issue has been edited by Steffen Freitag (Ruhr University Bochum), Rafi L. Muhanna (Georgia Institute of Technology) and Robert L. Mullen (University of South Carolina) and is based on the 7th International Workshop on Reliable Engineering Computing (REC 2016) held at Ruhr University Bochum in June 2016. The 11 papers of this special issue present new developments for the consideration of stochastic and non-stochastic uncertainties in various engineering and associated disciplines.

Gastvortrag zum Thema "Planung eines 200 m hohen Naturzugkühlturmes in China"
Dr.-Ing. Sebastian Höhler

Dr.-Ing. Sebastian Höhler von ZPP Ingenieure AG hält einen Gastvortrag mit dem Titel "Planung eines 200 m hohen Naturzugkühlturmes in China".

Kurzfassung:
Bei der Planung von Kühltürmen müssen neben der statischen Beanspruchung oft auch dynamische Beanspruchungen infolge Wind oder Erdbeben berücksichtigt werden. Diese Herausforderungen werden anhand eines 200 m hohen Kühlturms in China aufgezeigt.

Die Funktion des Kühlturms und die einzelnen Bauteile werden erläutert und die Grundlagen des Kühlturmdesigns(Formfindung und Lastannahmen) beschrieben.

Weiterhin wird die Modellierung des Kühlturms in einer Statiksoftware als 3D Gesamtmodell gezeigt. Davon ausgehend werden die bemessenen Bauteile anhand von Beispielen erläutert.

Der Vortrag wird während der Vorlesung "Baustatik 2" am 12.07.2018 um 10:15 Uhr im HIC stattfinden.

Splines for Discrete Crack Propagation in a Fluid-Saturated Porous Medium
Prof. Dr.ir.Dr.h.c. René de Borst (University of Sheffield, UK)

Prof. Dr.ir.Dr.h.c. René de Borst form the University of Sheffield, UK, will hold a guest lecture in the framework of SFB 837 about 'Splines for Discrete Crack Propagation in a Fluid-Saturated Porous Medium'.

Recently, isogeometric analysis has also been used for the analysis of crack propagation, also for discrete approaches. An elegant approach is to exploit the flexibility of NURBS (and T-splines) in increasing or lowering the order of continuity, which can be carried out in the parameter domain. While this facilitates the introduction of discontinuities, it puts some restrictions on the direction of crack propagation.

Apart from isogeometric interface elements, Powell–Sabin B-splines have been investigated to model discrete crack propagation. Different from NURBS and T-splines, this spline technology is based on triangles. Another difference is that the crack is now directly introduced in the physical domain. Since triangles and Bézier extraction are used, re-meshing is straightforward, and standard algorithms can be used for this purpose.

Different from smeared approaches, discrete crack modelling allows for the straightforward description of mass transport in cracks, as for instance occurs in a fluid-saturated porous medium. A multiscale model is derived. The resulting two-scale model imposes some requirements on the interpolation of the displacement and the pressure fields, which can be satisfied elegantly using spline basis functions.
