In this paper, a new method is introduced which involves the attachment of a smear radius to 1D drainage elements. This allows for automatic reduction of kh at mesh integration points that fall within the smear zone, as well as the consideration of non-uniform hydraulic properties. The results of analyses carried out for a unit cell with a single PVD and smear zone show that the new method achieves the same accuracy as the case where the smear zone is modelled as a separate meshed region.]]> Wed 11 Sep 2019 11:53:47 AEST ]]> On the application of high-order elements in large deformation problems of geomechanics https://ogma.newcastle.edu.au/vital/access/

Comparison of a strength reduction technique with rigorous finite element limit analysis confirms that the factors of safety (FoS) obtained are very similar for associated plasticity, an intrinsic assumption of limit analysis. For non-associated plasticity, a modified version of the so-called Davis approach has been applied because it has been shown that the original formulation proposed by Davis works well when the FoS is defined in terms of loads but is not appropriate when the FoS is defined in terms of soil strength. The results show that, with the modified Davis parameter, both strength reduction finite element analyses and finite element limit analyses provide very similar factors of safety. The key advantage of limit analysis, however, is that the value of the FoS can be bracketed from above and below with upper and lower bound calculations.]]> Sat 24 Mar 2018 07:12:35 AEDT ]]> Explicit stress integration with streamlined drift reduction https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25067 Sat 24 Mar 2018 07:10:42 AEDT ]]> Discrete modelling jointed rock slopes using mathematical programming methods https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42622 Mon 29 Aug 2022 09:21:12 AEST ]]> Preliminary tests of a new low-cost photogrammetric system https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32427 Mon 23 Sep 2019 10:45:20 AEST ]]> Advancing Australia's facilities for physical modelling in geotechnics https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18648 Mon 20 Jul 2015 16:59:21 AEST ]]> One-dimensional test problems for dynamic consolidation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25694 Mon 17 Jun 2019 13:05:45 AEST ]]> Undrained stability of a single circular tunnel in spatially variable soil subjected to surcharge loading https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33783 Mon 14 Jan 2019 17:41:46 AEDT ]]> A novel web based application for storing, managing and sharing geotechnical data, illustrated using the national soft soil field testing facility in Ballina, Australia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42855 Mon 05 Sep 2022 15:54:33 AEST ]]> Undrained stability of an unlined square tunnel in spatially random soil https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34240 Fri 22 Feb 2019 14:42:15 AEDT ]]> A low-cost terrestrial photogrammetric system for rockfall monitoring and hazard assessment in open-pit mines https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42769 Fri 02 Sep 2022 10:04:37 AEST ]]>
