Due to the inherent nonlinearity, crashworthiness is one of the most demanding design cases for vehicle structures. Recent developments have enabled very accurate numerical simulations and corresponding optimizations. Therefore, ...

The H-point of a seat is an important parameter for in the design process of a vehicle, and in particular the design of a seat. This can be estimated empirically, but this method is usually not sufficient to accurately determine how ...

Composite materials with textile reinforcements are showing rapid growth of integration in aerospace, automotive, sport and other industrial sectors. Especially non-crimp fabrics (NCF) are widely spread because of their high ...

Textile materials are increasingly used in civil engineering for the purpose of reinforcing high performance composites, acting as membranes or fulfil technical tasks like filter contaminated media. Therefore, the demand for accurate ...

Im Rahmen eines Forschungsvorhabens an der Hochschule für Technik und Wirtschaft in Aalen wird das plastische Umformverhalten von hochfesten Stählen, insbesondere Federstählen, untersucht. Im Detail stehen neben der klassischen ...

In this study, a process for assessing the robustness of designs has been presented, and the results are discussed using front structures of a vehicle FE model as an example. Statistical approaches have been introduced in order to ...

To improve efficiency in automotive press shops, press systems with increasingly high stroke rates are being implemented, raising thereby the structural dynamic load on the press and especially on the forming tool. A detailed ...

Recently vehicle model is becoming more detailed and complex. Due to refinement of vehicle model, automotive companies are demanding to directly evaluate dummy injury criteria in crush analysis. To evaluate injury criteria, more ...

So far analytical and, to a lesser extent, numerical approaches have been limited in their ability to predict the properties of braided composites because of the high complexity of the rovings’ interlacing. While many analytical ...

The investigations described here are related to the unstable behavior of crash-simulations due to minor changes in the model. As a consequence the received simulation results become in some way unpredictable, whereby the causes can ...
