Research

PhD project: A Light-Weight Carbody for High-Speed Trains , a project under the centre for ECO² Vehicle Design. The goal of the project is to lower the overall weight and manufacturing cost of the car body for a high-speed train by utilizing modern sandwich technique. Focus is on the mechanical behavior of such a design whilst keeping in mind other important boundary conditions.
