Drop tower crash test of reference steel side sill structure Crash simulation model of complete Body-in-White

The Korea Evaluation Institute of Industrial Technology in hybrid multi-material design and consists of B-pillar,
(KEIT) has launched a joint research project with Korean roof-rail and side-sill. In a side impact, this structural part

tute of Lightweight Engineering and Polymer Technology sengers from serious injuries. The aim of the project is to
of the TU Dresden, in which a new lightweight vehicle side build this structure in hybrid multi-material lightweight
structure and associated highly efficient production pro- construction, which is at least 25 percent lighter than a
cesses are to be developed. As part of this project, the ILK conventional module with at least the same performance.
focuses on simulation methods and design strategies for
the design of such a side structure in the event of side-
crash. The use of high-performance computing resources
at ZIH Dresden makes it possible to carry out realistic and Supervised by:
computationally intensive crash simulations at compo-
nent and vehicle level to efficiently assist the design and
dimensioning process. The side structure itself is designed
