20.500.12556/RUL-124376 Determination of stress-strain behaviour of magnesium alloy AZ31 under variable thermomechanical loading Growing environmental demands and higher fuel efficiency encourage the use of new light-weight load-bearing materials even for operation under rougher environmental conditions. Consequently, as the materials used in the vital load-bearing components of the chassis, brake system or exhaust system are subjected to thermomechanical fatigue during the operation due to variable mechanical and thermal loads, it is crucial for design engineers and CAE analysts to understand the cyclic behaviour of new materials under such conditions. Here we have analysed the stress-strain behaviour of magnesium alloy AZ31 and the influence of variable thermomechanical loads. A uniaxially loaded flat specimen has been first mechanically loaded at -25°C. The temperature was then increased to 150°C whilst the variable mechanical loading remained unchanged. The tests have been strain-controlled using a video extensometer. The stress-strain behaviour of the magnesium alloy AZ31 has been then investigated considering both variable temperature and variable mechanical load. dissipated energy durability magnesium alloy AZ31 stress-strain behaviour thermomechanical fatigue disipirana energija zdržljivost magnezijeva zlitina AZ31 napetostno-deformacijsko obnašanje termomehansko utrujanje true false false Angleški jezik Slovenski jezik Članek v reviji 2021-01-19 11:52:23 2021-01-19 11:52:26 2022-09-04 03:59:07 0000-00-00 00:00:00 2021 0 0 f. 1125-1133 iss. 4 Vol. 44 2021 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2022-01-19 620.178.3:669.721.5(045) 1460-2695 10.1111/ffe.13417 47629571 RAZ_Seruga_Domen_2021.pdf RAZ_Seruga_Domen_2021.pdf 1 0E924ACA252AF43F057D6AC6C6CA94D8 160af5d71890a4c98988a7c795c9d8e33975bbb0ebc03e75112236e83e7cd2c2 89c4bd27-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=139818 https://onlinelibrary.wiley.com/doi/10.1111/ffe.13417 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=139817 Fakulteta za strojništvo 0 0 0
