20.500.12556/DKUM-27311 In-service damage of railway steel axles Oštećenje na čeličnoj tračničkoj osovini u eksploataciji The influence of temperature and specimens undercut place on impact toughness of railway axle material in service is investigated. The obtained results show inversely proportional dependence of impact toughness on undercut radius of specimens. The decrease of test temperature from +20 to –40 ºC decreases significantly the impact toughness and portion of ductile fracture. U radu je istražen utjecaj temperature i mjesta zajeda uzorka na udarnu žilavost materijala tračničke osovine u eksploataciji. Dobiveni rezultati pokazuju obrnutu proporcionalnost ovisnosti udarne žilavosti o polumjeru zajeda na uzorcima. Smanjenjem temperature ispitivanja od +20 to –40 ºC značajno se smanjuje udarna žilavost i udio žilavog loma. impact toughness in-serice damage railway axle undercut udarna žilavost poškodbe pri obratovanju železniške osi zajeda true false true Angleški jezik Hrvaški jezik Znanstveno delo 2012-06-01 10:27:49 2012-06-01 10:27:49 2022-04-15 13:42:08 2022-03-30 03:06:09 2011 0 0 str. 87-90 št. 1 Letn. 18 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1330-3651 625.143.2.042.2:620.17 15346181 14885910 1330-3651 URN:SI:UM:DK:CIDNPDWL Tehnicki_vjesnik_2011_Jasnìî_et_al._In-service_damage_of_railway_steel_axles.pdf Tehnicki_vjesnik_2011_Jasnìî_et_al._In-service_damage_of_railway_steel_axles.pdf 1 4606FD432F521110AF47F8417F3C0D3F ca3bbe44fdeadd29396ab0c8061311f676a7cda719f1833c0f0f68bcfe244a08 65ebce68-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/bcbf8e91-d28d-42e3-8f1c-c3096e7e47c7 https://dk.um.si/Dokument.php?lang=slv&id=114035 http://hrcak.srce.hr/65930 1 https://dk.um.si/Dokument.php?lang=slv&id=36590 Fakulteta za strojništvo 0 0 0
