The fields of application are One-of-a-Kind products and industrial prototypes. The first example is taken from the problem area of typically high complex capital goods being virtually modelled and simulated prior to the real setting-up. The strategy of complimentarily developing both, the prototype’s mechanics and its functionality and the issues of concurrent and distributed team-work are characterised. Enabling technologies for the iterative setting-up of the real prototype are described with reference to practical experience. The second example is the virtual and the touchable prototyping of sheet metal parts, incorporating the FEM simulation of the process as well as the closed prototyping chain for a fast verification of the results. An enabling technology is the triangulation of parametric CAD surface models, a technique to represent random solid bodies as a polyedrical mesh, from which “real” and “virtual”...

As a consequence of this, fibre reinforced polymers often have a higher risk of being exposed to impact loads. Sudden unheralded structural failure of FRP caused by primary damage induced by impact loads is an important Factor especially in the aircraft industry. A prognosis of damage caused by barely visible impacts is difficult to predict. Especially in consideration of the fact that barely visible impacts and therewith possible primary damages are often unrecognized. The knowledge of the mechanisms and of the material loading during and shortly after an impact load is an important factor for the development of an "impact load monitoring system". The impact load can be reconstructed completely by means of several discrete measurement points. The location of the primary impact and furthermore the impact strength, the contact time and the feasibility of possible damages are evaluated with the impact load monitoring system.
