to the Research Seminar 'Computer Graphics, Image Processing, and 
Visualization'

     onWednesday, October 14th, 2015, at 1:15 PM,
     in Room P-701 in the Paulinum, Augustusplatz.

The talk is given by

     Valentin Zobel
     Image and Signal Processing Group
     Institute of Computer Science
     Leipzig University

and is entitled

     "Feature-Based Tensor Field Visualization for Fiber Reinforced 
Polymers".

Abstract:

     Virtual testing is an integral part of modern product development in
     mechanical engineering. Numerical structure simulations allow the
     computation of local stresses which are given as tensor fields. For
     homogeneous materials, the tensor information is usually reduced to a
     scalar field like the von Mises stress. A material-dependent threshold
     defines the material failure answering the key question of 
engineers. This
     leads to a rather simple feature-based visualisation. For composite
     materials like short fiber reinforced polymers, the situation is 
much more
     complex. The material property is determined by the fiber 
distribution at
     every position, often described as fiber orientation tensor field.
     Essentially, the material's ability to cope with stress becomes 
anisotropic
     and inhomogeneous. We show how to combine the stress field and the 
fiber
     orientation field in such cases, leading to a feature-based 
visualization
     of tensor fields for composite materials. The resulting features 
inform the
     engineer about potential improvements in the product development.


On behalf of Professor Scheuermann all those interested are cordially 
invited to attend.


Yours sincerely,

Tom Liebmann
