Both static and dynamic loads were applied to the rock specimens to investigate the mechanism of fracture evolution around the cavities for different lateral pressure coefficients. In addition, characteristics of acoustic emission (AE) associated with fracture evolution were simulated. Finally, the evolution and interaction of fractures between multiple cavities were investigated with consideration of stress redistribution and transference in compressive and tensile stress fields. The numerically simulated results reproduced primary tensile, remote, and shear crack fractures, which are in agreement with the experimental results. Moreover, numerical results suggested that both compressive and tensile waves could influence the propagation of tensile cracks; in particular, the reflected tensile wave accelerated the propagation of tensile cracks.]]> Wed 11 Apr 2018 13:17:24 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:8025 Sat 24 Mar 2018 08:36:49 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:12508 Sat 24 Mar 2018 08:18:42 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:12506 max) plays an important role in the failure process of specimens with two indenters. Furthermore, the heterogeneity of the rock can also affect the failure modes of the rock when two indenters are used. Finally, the numerical results demonstrate the effect of the spacing between the indenters on the rock.]]> Sat 24 Mar 2018 08:15:54 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:19256 Sat 24 Mar 2018 08:06:38 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:16726 Sat 24 Mar 2018 08:05:32 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:16866 Sat 24 Mar 2018 07:54:48 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:16871 Sat 24 Mar 2018 07:54:48 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:16849 Sat 24 Mar 2018 07:53:31 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25475 Sat 24 Mar 2018 07:31:57 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25657 max) on the failure mechanism of brick masonry is considered.]]> Sat 24 Mar 2018 07:28:09 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:22179 Sat 24 Mar 2018 07:16:24 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:22182 Sat 24 Mar 2018 07:16:23 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:22093 Sat 24 Mar 2018 07:15:15 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24733 Sat 24 Mar 2018 07:10:58 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26734 Mon 19 Aug 2024 10:31:06 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34650 Mon 08 Apr 2019 13:03:16 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32756 Fri 20 Jul 2018 16:27:15 AEST ]]>
