Collisions of ships, impact of foreign objects on aeroplanes and crashes of ground vehicles are some examples of accidents which can have severe effects on humans lives and health as well as on the environment. To avoid catastrophic consquences of such accidents is a key in transportation industry as well as for insurance companies and it continuously requires the investment of a vast amount of economical resources. Extremely expensive full component tests are performed to prove the safety of structures. In many cases, the safety reserves of structures remain unknown so that too high safety factors limit any efficient exploitation of materials. Improvements in efficiency and quality of technical systems have to start during the conceptual phase of the design process, already. This requires advanced design and analysis methods and tools, including simulation techniques and computational prototyping. The development of numerical models for the simulation of the mechanical behaviour of structures in various scenarios of possible accidents is therefor a main objective of present research in the field of structural assessment. In order to provide experimental for calibrating the respectivenumerical models GKSS has build up a test facility to investigate the deformation, damage and failure of metal sheets under penetration. The present paper describes the test set-up as well as the numerical modelling ao bi-axially loaded steel sheets which are punched perpendicular to the plane of the sheet.
