One of the most important approaches is the implementation of lightweight constructions. Therefore, the usage of high performance materials with tailored properties gains importance. For safety-relevant components such as automotive passenger cells it is necessary to minimize deformation to reduce the risk of injury for the vehicle occupants during a car accident. Thus, hot stamped high-strength steels have been established. High-strength and low formability of this kind of materials represent new challenges for joining technologies. One possibility to join high-strength steels is the newly developed shear-clinching technology. Due to the use of a combined cutting and joining process, the connection of dissimilar materials with high difference in strength and formability can be achieved. Further research to ensure process reliability and to improve the strength of the joint is required. One possible approach for this is the numerical investigation of the material flow during the joining process. Therefore, the definition of process parameters for the finite element model is necessary. A big impact on the quality of the results has the accuracy of the used friction values. As established testing methods are not suitable for modeling the rather complex tribological system between the joining partners of the shear-clinching process, an innovative testing method is needed. Studies in the field of sheet-bulk metal forming already demonstrated the applicability of the ring compression test for sheet metals. This paper presents a concept for the adaption of the ring compression test to the specific needs of the investigated shear-clinching process. The numerical identification of the friction coefficients is validated by experimental data and first results are qualified by experimental and simulative shear-clinching joints.}}, author = {{Müller, Martin and Vierzigmann, Ulrich and Hörhold, Réjane and Meschut, Gerson and Merklein, Marion}}, issn = {{1662-9795}}, journal = {{Key Engineering Materials}}, keywords = {{Mechanical Engineering, Mechanics of Materials, General Materials Science}}, pages = {{469--476}}, publisher = {{Trans Tech Publications, Ltd.}}, title = {{{Development of a Testing Method for the Identification of Friction Coefficients for Numerical Modeling of the Shear-Clinching Process}}}, doi = {{10.4028/www.scientific.net/kem.639.469}}, volume = {{639}}, year = {{2015}}, } @inproceedings{21467, author = {{Homberg, Werner and Rostek, Tim}}, title = {{{Innovative Processing Techniques for the Manufacture of High-Performance Active Elements from Ultra High-Strength Steel Plate}}}, year = {{2015}}, } @article{21516, abstract = {{This study presents the results of an experimental investigation of the influence of latent thermal heat storage elements on the power consumption as well as the temperature distribution of commercial household refrigerators.Two evaporator types and a standard wireand- tube condenser are equipped with copolymer-bound phase change materials (PCM) and the performance is determined under standard conditions. The results show that refrigerating appliances equipped with PCM can be optimized through modifications of the control strategy to achieve different targets: (a) Power consumption can be significantly reduced by increasing the evaporator and decreasing the condenser temperature. (b) Temperature fluctuations in the refrigerator’s fresh-food compartment during the cooling cycle can be reduced from 4 °C to 0.5 °C. (c) The cooling cycle duration can be tripled without compromising the fresh-food compartment conditions. The latter may help to meet the growing demand for balancing power consumption to stabilize the power grid, e.g. if the share of highly fluctuating, sustainable energy supply is large.}}, author = {{Sonnenrein, Gerrit and Baumhögger, Elmar and Elsner, Andreas and Fieback, K. and Morbach, A. and Paul, Andreas and Vrabec, J.}}, issn = {{0140-7007}}, journal = {{International Journal of Refrigeration}}, pages = {{166--173}}, title = {{{Copolymer-bound phase change materials for household refrigerating appliances: experimental investigation of power consumption, temperature distribution and demand side management potential}}}, doi = {{10.1016/j.ijrefrig.2015.06.030}}, volume = {{60}}, year = {{2015}}, } @inproceedings{21454, abstract = {{In order to optimise the material utilisation and improve the lightweight design of automotive parts tailored hollow profiles are needed, especially as semi-finished parts for hydroforming.
