Introduction into Finite Plasticity with Application in Crash Simulations

The Faculty of Informatics is pleased to announce a two-part seminar given by Raphael Prohl

TITLE: Introduction into Finite Plasticity with Application in Crash Simulations
DATE: Tuesday June 28th and Thursday June 30th, 2011
PLACE: USI Università della Svizzera italiana, room SI-004, Black building (Via G. Buffi 13)
TIME: 10.30

ABSTRACT:
CAE-simulations allow us to recognize and evaluate the characteristics of a vehicle on the basis of a simulation at an early stage without the need to build a real prototype. Already at the design engineering stage long before the rst prototypes can be tested, we
need reliable knowledge about the vehicles characteristics. Advances in applied mechanics, numerical methods and computer technology today permit the simulation of complex phenomena of automotive engineering.
Crash simulations are highly sensitive numerical experiments, this means small changes in the input can partly lead to large changes in the deformation behavior of the car. On the other hand, physical instabilities due to, for example bifurcation behavior of the material, can appear and have to be captured and correctly solved by the numerical procedures in order to obtain reliable results.
This talk introduces into the basic theory of Finite Plasticity, which describes the irreversible material processes at large deformations. In a second session an insight into the algorithmic treatment of plasticity in current industrial simulations will be delivered.

BIO:
Raphael Prohl is a phd-student in Informatics at the Goethe-Center for Scientific Computing (GCSC, head: Prof. Gabriel Wittum, University of Frankfurt (Germany)). He finished his studies of Scientific Computing at the University of Heidelberg in July 2010. Since August 2010 he has been employed at the Steinbeis-Center for Innovation, Simulation in Technology, working on the project "Reduction of numerical sensitivities in Crash Simulations on High-Performance-Computers". Currently he stays in Lugano for a research visit at the group of Prof. Rolf Krause with respect to contact simulations
and plasticity.
