Identification of a GTN Damage Model Parameter set Using
HyperStudy
Matthias Schneider, Mannesmann Salzgitter Forschung
The damage model based on Gurson, Tveergard and Needleman
is nowadays often used in finite element analysis.
There are different possible ways for the identification
of the numerous
parameters. In this approach, HyperStudy was
used to achieve a first experience of the uniqueness
and effects of the parameter
sets.
