Katerina Giannoukou’s secondment at the Technical University of Munich (TUM)

Katerina Giannoukou has recently completed a 3-month stay in Munich as part of the external page GREYDIENT project. During this period, she joined the Computational Solid Mechanics research group

at TUM (external page Prof. Fabian Duddeck) as a visiting student. Katerina's main focus was on exploring applications of multi-fidelity approaches in crashworthiness.

Specifically, Katerina worked on a transfer learning scenario that involved crash simulations for two different crash boxes. Her objective was to assess the possibility of developing an effective surrogate model for one of the crash boxes using a limited number of simulations, by making use of pre-existing simulations of the other crash box.

Katerina found that, in situations where the two crash boxes share enough similarities, employing multi-fidelity surrogate models with knowledge from one of the crash boxes proves to be more advantageous in creating a surrogate for the other one than traditional single-fidelity surrogate models. These promising results could pave the way for broader adoption of multi-fidelity surrogate modelling techniques in crashworthiness simulations.
