Over the recent years the importance of numerical experiments has gradually been more recognized. Nonetheless, sufficient documentation of how computational results have been obtained is often not available. Especially in the scientific computing and applied mathematics domain this is crucial, since numerical experiments are usually employed to verify the(More)
Background: Car crash simulations need a lot of computation time. Model reduction can be applied in order to gain time-savings. Due to the highly nonlinear nature of a crash, an automatic separation in parts behaving linearly and nonlinearly is valuable for the subsequent model reduction. Methods: We analyze existing preprocessing and clustering methods(More)
Hintergrund. Bewegte Umfeldreize treten bei visuellen Aufgaben gelegentlich auf. In welcher Weise beeinflussen Umfeldreize die Augenbewegungen beim Lesen eines Textes? Methode. Bei 30 Normalpersonen mit regelrechter Sehschärfe wurden die Lesebewegungen eines standardisierten Textes elektronystagmographisch abgeleitet. Der stumm zu lesende Text befand sich(More)
BACKGROUND In the state of the art finite element AHBMs for car crash analysis in the LS-DYNA software material named *MAT_MUSCLE (*MAT_156) is used for active muscles modeling. It has three elements in parallel configuration, which has several major drawbacks: restraint approximation of the physical reality, complicated parameterization and absence of the(More)
This contribution presents a structural optimization loop comprising reduced elastic multibody system simulation, finite element models and durability analysis. Whereas conventional approaches in this field require a postprocessing of elastic multibody system results, the presented work allows the calculation of damage values during runtime of the elastic(More)
The purpose of this project is to improve the development process of vehicle safety systems by introducing a new analytic approach. Today, the development of vehicle safety systems, especially the airbag design process, requires many iteration loops via simulations and experiments. In this process, parameters are changed, a new simulation is conducted and(More)
