20.500.12556/DKUM-27043 Modelling of surface crack growth under lubricated rolling-sliding contact loading The paper describes modelling approach to computational simulation of surface crack growth subjected to lubricated rolling-sliding contact conditions. The model considers the size and orientation of the initial crack, normal and tangential loading due to rolling-sliding contact and the influence of fluid trapped inside the crack by a hydraulic pressure mechanism. The motion of the contact sliding load is simulated with different load cases. The strain energy density (SED) and maximum tangential stress (MTS) crack propagation criteria are modified to account for the influence of internal pressure along the crack surfaces due to trapped fluid. The developed model is used to simulate surface crack growth on a gear tooth flank, which has been also experimentally tested. It is shown that the crack growth path, determined with modified crack propagation criteria, is more accurately predicted than by using the criteria in its classical form. fracture mechanics numerical methods contact loading finite element analysis internal pressure maximum tangential stress strain energy density surface crack growth mehanika loma kontaktne obremenitve analiza končnih elementov notranji tlaki največje obodne napetosti gostota deformacijske energije rast razpoke true false false Angleški jezik Angleški jezik Neznano 2012-06-01 09:41:49 2012-06-01 09:41:49 2022-04-15 03:43:18 2019-07-10 12:10:59 2005 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.42:519.61/.64 9770006 0376-9429 URN:SI:UM:DK:45IK3ADN http://www.springerlink.com/openurl.asp?genre=article&id=doi:10.1007/s10704-005-8546-8 1 https://dk.um.si/Dokument.php?lang=slv&id=36279 Fakulteta za strojništvo 0 0 0
