20.500.12556/RUL-134704 Incorporation of a simplified mechanical joint model into numerical analysis Vključitev poenostavljenega modela mehanskega spoja v numerično analizo In the development of new joining technologies, incorporation of mechanical joints in computer analyses for the evaluation of structures can be carried out by a practical, simplified mechanical joint model. Here, two most frequently used joining technologies were analysed, a self-piercing rivet joint and a clinch joint. Physical tests of static load capacity of the joints were performed and numerical models for simulations were set-up. An optimization method was designed for estimating the material parameters of the mechanical joint for the needs of numerical analyses. For optimization purposes during the plan of experiments, a range of possible parameter values was investigated using a response surface method, results of simulations, results of physical tests and a genetic algorithm. The results of simulations using the optimal values of the material parameters are comparable to the experimental observations for the both joints. mechanical joints self-piercing riveting clinch joints parameter optimization simplified FE model response surface genetic algorithm zagozdni spoji mehanski spoji samorezno kovičenje metoda končnih elementov optimizacija parametrov odzivna površina genetski algoritem true false true Angleški jezik Slovenski jezik Članek v reviji 2022-01-27 09:19:47 2022-01-27 09:19:51 2022-09-13 03:56:40 0000-00-00 00:00:00 2022 0 0 Str. 3-13 no. 1 Vol. 68 Jan. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.62 0039-2480 10.5545/sv-jme.2021.7329 95180547 RAZ_Glavan_Mitja_2022.pdf RAZ_Glavan_Mitja_2022.pdf 1 E01EA184AD22B512F0BC01B25A015B05 01b7760b51a4286109b4eeab0290b942180595ff4e9fe40fd6095a743a0211dd 09ff3669-7f4a-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153288 https://www.sv-jme.eu/sl/article/incorporation-of-a-simplified-mechanical-joint-model-into-numerical-analysis/ 1 b3031e42-7f49-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153287 Fakulteta za strojništvo Strojniški vestnik 0 0 0
