The time-temperature evolution during the welding cycle was measured experimentally and modelled with the softwaretool SimWeld. To model the phase transformations during the welding cycle dilatometer tests were done to quantify the parameters for phase field modelling by MICRESS®. The important input parameters are interface mobility, nucleation density, etc. A contribution was made to include austenite to bainite transformation in MICRESS®. This is useful to predict the microstructure in the fast cooling segments. The phase transformation model is capable to predict the microstructure along the heating and cooling cycles of welding. Tensile tests have shown the evidence of failure at the heat affected zone, which has the ferrite-tempered martensite microstructure.}, language = {en} } @article{MukherjeeRamazaniYangetal.2011, author = {Mukherjee, Krishnendu and Ramazani, Ali and Yang, Li and Prahl, Ulrich and Bleck, Wolfgang and Reisgen, Uwe and Schleser, Markus and Abdurakhmanov, Aydemir}, title = {Characterization of gas metal arc welded hot rolled DP600 steel}, series = {Steel research international}, volume = {Vol. 82}, journal = {Steel research international}, number = {Iss. 12}, publisher = {Wiley}, address = {Weinheim}, issn = {1869-344X (E-Book); 1611-3683 (Print)}, pages = {1408 -- 1416}, year = {2011}, language = {en} } @inproceedings{NakagawaKallweitMichauxetal.2016, author = {Nakagawa, Masaki and Kallweit, Stephan and Michaux, Frank and Hojo, Teppei}, title = {Typical Velocity Fields and Vortical Structures around a Formula One Car, based on Experimental Investigations using Particle Image Velocimetry}, series = {SAE International Journal of Passenger Cars - Mechanical Systems}, booktitle = {SAE International Journal of Passenger Cars - Mechanical Systems}, issn = {1946-4002}, doi = {10.4271/2016-01-1611}, pages = {18 S.}, year = {2016}, language = {en} } @inproceedings{NakagawaMichauxKallweitetal.2015, author = {Nakagawa, Masaki and Michaux, Frank and Kallweit, Stephan and Maeda, Kazuhiro}, title = {Unsteady flow measurements in the wake behind a wind-tunnel car model by using high-speed planar PIV}, series = {11TH International Symposium on Particle Image Velocimetry - PIV15 Santa Barbara, California, September 14-16, 2015}, booktitle = {11TH International Symposium on Particle Image Velocimetry - PIV15 Santa Barbara, California, September 14-16, 2015}, pages = {21 S.}, year = {2015}, abstract = {This study investigates unsteady characteristics of the wake behind a 28\%-scale car model in a wind tunnel using highspeed planar particle image velocimetry (PIV). The car model is based on a hatchback passenger car that is known to have relatively high fluctuations in its aerodynamic loads. This study primarily focuses on the lateral motion of the flow on the horizontal plane to determine the effect of the flow motion on the straight-line stability and the initial steering response of the actual car on a track. This paper first compares the flow fields in the wake behind the above mentioned model obtained using conventional and high-speed planar PIV, with sampling frequencies of 8 Hz and 1 kHz, respectively. Large asymmetrically coherent flow structures, which fluctuate at frequencies below 2 Hz, are observed in the results of highspeed PIV measurements, whereas conventional PIV is unable to capture these features of the flow owing to aliasing. This flow pattern with a laterally swaying motion is represented by opposite signs of cross-correlation coefficients of streamwise velocity fluctuations for the two sides of the car model. Effects of two aerodynamic devices that are known to reduce the fluctuation levels of the aerodynamic loads are then extensively investigated. The correlation analyses reveal that these devices indeed reduce the fluctuation levels of the flow and the correlation values around the rear combination-lamp, but it is found that the effects of these devices are different around the c-pillar.}, language = {en} } @misc{Nordmann2022, type = {Master Thesis}, author = {Nordmann, Alexander}, title = {Prozess{\"u}berwachung beim Werkzeugschleifen von WC-Co Hartmetallschaftfr{\"a}sern}, publisher = {FH Aachen}, address = {Aachen}, school = {Fachhochschule Aachen}, pages = {xi, 54 Seiten}, year = {2022}, language = {de} } @inproceedings{OttenGerhardsSchleseretal.2019, author = {Otten, Christian and Gerhards, Benjamin and Schleser, Markus and Schwarz, A. and Gebhardt, Andreas}, title = {Innovative Laserschweißtechnologie f{\"u}r additiv gefertigte Bauteile}, series = {Große Schweißtechnische Tagung}, booktitle = {Große Schweißtechnische Tagung}, publisher = {DVS-Media}, address = {D{\"u}sseldorf}, isbn = {978-3-96144-066-5}, pages = {150 -- 157}, year = {2019}, language = {de} } @inproceedings{PakPiegelerFeldmannetal.2006, author = {Pak, Daniel and Piegeler, D. and Feldmann, Markus and Schleser, Markus and Dilthey, Ulrich}, title = {Hybrid joints of textile reinforced concrete parts - designed for assembly}, series = {Textile reinforced concrete : proceedings of the 1.
