20.500.12556/DKUM-27383 Investigation of crack propagation scatter in a gear tooth's root This paper describes the problem of determining crack initiation location and its influence on crack propagation in a gear tooth's root. Three different load positions on the gear tooth's flank were considered for this investigation of crack initiation and propagation. A special test device was used for the single tooth test. It can be concluded from the measurements thata crack can be initiated at very different locations in a tooth's root and then propagate along its own paths. A numerical investigation into a crack initiation's position and its influences on its propagation were carried out within the framework of linear fracture mechanics. The influence of a tooth's load position, the geometry of the tooth's root, and the influence of nonparallel load distribution on the tooth's flank were considered when investigating the crack initiation's position. Results show that linear fracture mechanics can be used for determining crack propagation, if better initial conditions for crack initiation are considered. fracture mechanics crack initiation experimental crack propagation numerical crack propagation crack location gearbox tooth root load distribution linear elastic fracture mechanics lomna mehanika nastanek razpoke širjenje razpoke eksperimentalno širjenje razpoke numerično širjenje razpoke kraj razpoke menjalnik koren zoba porazdelitev obremenitve sledi rezala linearna elastična mehanika loma true false false Angleški jezik Angleški jezik Neznano 2012-06-01 10:55:29 2012-06-01 10:55:29 2022-04-15 03:44:14 2019-07-10 12:15:59 2008 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.42:621.83-585.1 11211542 0013-7944 URN:SI:UM:DK:PYCHZFBG http://dx.doi.org/10.1016/j.engfracmech.2007.04.005 1 https://dk.um.si/Dokument.php?lang=slv&id=36677 Fakulteta za strojništvo 0 0 0
