The following is an excerpt.
The 12th European LS-DYNA Conference in Koblenz is said to be a big success. Eight SIMLab and SFI CASA people took the opportunity to present their work at the conference.
The attendants gave more than 200 presentations during the 12th European LS-DYNA Conference in Germany. Out of these, researchers from SIMLab and SFI CASA presented eight papers, including professor Odd Sture Hopperstad´s keynote presentation.
Close to 500 participants in Koblenz
The user community of LS-DYNA developers, industry users and academia met for presentations, workshops, discussions and seminars 14-16 May. The event took place in the historic city of Koblenz, Germany. Close to 500 participants could choose among more than 200 technical presentations on all LS-DYNA applications.
Also, the organizer called special attention to this year´s group of renowned keynote speakers from industry and academia all over the world «that proves the high quality of the conference»:
Niclas Brännberg (NIO), Prof. Odd Sture Hopperstad (NTNU), Johan
Towards a Virtual Laboratory
The title of Professor Odd Sture Hopperstad´s presentation was «Towards a Virtual Laboratory for Aluminium Structures». Hopperstad leads the Toppforsk project FractAl, and the microstructure-based modelling approach has been developed in a joint effort with CASA. The long-term objective of this activity is to establish a virtual laboratory for the design of aluminium structures in the ultimate limit state and accidental limit state.
