20.500.12556/RUL-105273 Validation of linear damage rules using random loading Fatigue damage is a parameter which plays an important role in lifetime and reliability predictions of randomly loaded structures. In this paper, four different forms of the Miner linear accumulation damage rule are examined. They are used to compare observed experimental damage and the results of numerical simulations for both uniaxial and multiaxial fatigue. First, critical fatigue damage values for all forms of the Miner accumulation damage rule are calculated for uniaxial cases. Based on the results presented in this paper, it has been established that for high strength materials the critical damage value is around 0.3. These results are then applied to the multiaxial cases. The multiaxiality is taken into account using either the signed von Mises or critical plane method. Finally, the fatigue fracture surface has been calculated and compared to the experimental pattern of fatigue fracture. The results show that the fatigue fracture surface determined by the numerical simulation is comparable to the fatigue fracture observed experimentally. damages multiaxial fatigue critical plane signed von Mises poškodbe večosnost utrujanje kritična ravnina true false true Angleški jezik Slovenski jezik Članek v reviji 2018-11-19 09:28:41 2018-11-19 09:28:42 2025-03-06 10:43:38 0000-00-00 00:00:00 2017 0 0 Str. 463-479 iss. 3 Vol. 26 2017 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2016-09-18 531(045) 1056-7895 10.1177/1056789515605881 14219547 RAZ_Franko_Mitja_i2017.pdf RAZ_Franko_Mitja_i2017.pdf 1 67EEAE7F7C5E4B08B34393EE66A7441D 7689c3277f1a267ba240d1a7fe335a90f3ddfe4620182ca6fd3907e2f2ec452d 281cf1ae-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=115899 http://journals.sagepub.com/doi/abs/10.1177/1056789515605881 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=115898 Fakulteta za strojništvo 0 0 0
