20.500.12556/RUL-108298 A direct approach to modelling the complex response of magnesium AZ31 alloy sheets to variable strain amplitude loading using Prandtl-Ishlinskii operators A new approach to modelling the complex behaviour of magnesium AZ31 alloy subjected to arbitrary uniaxial cyclic loading is introduced. Based on the Prandtl-Ishlinskii rheological model, one side play operators are applied so as to simulate the ascending and descending parts of asymmetric hysteresis loops separately. From the known material response to constant amplitude uniaxial loading, the Prandtl-Ishlinskii rheological model gives a fast and accurate simulation of the magnesium AZ31 alloy sheets response to arbitrary uniaxial loading under isothermal conditions. The approach represents a valuable starting point for estimating fatigue life using the energy approach for magnesium alloys. uniaxial cyclic loading variable amplitude loading magnesium alloys AZ31 Mg material model rheological model one side play operators Prandtl-Ishlinskii operators enoosno obremenjevanje obremenjevanje s spremenljivo amplitudo magnezijeve zlitine materialni modeli reološki modeli enostranski operatorji Prandtl-Ishlinskii operatorji true false true Angleški jezik Slovenski jezik Članek v reviji 2019-06-27 13:51:17 2019-06-27 13:51:21 2025-03-18 11:39:22 0000-00-00 00:00:00 2019 0 0 Str. 291-304 Vol. 127 Oct. 2019 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2021-06-15 531:621.86.01:669.721.5(045) 0142-1123 10.1016/j.ijfatigue.2019.06.009 16674075 25643520 RAZ_Solinc_Ursa_i2019.pdf RAZ_Solinc_Ursa_i2019.pdf 1 1E8A1F7014688A4DD2DC6DC07E6BE45D d2cf14043622ee5bb60638ccbcfac9a75c860beb31e1dcdc2d5defde742fca51 9d6239e2-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=119252 https://www.sciencedirect.com/science/article/pii/S0142112319302397 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=119251 Fakulteta za strojništvo 0 0 0
