Fracture networks in sea ice
Vevatne, Jonas Nesland; Rimstad, Eivind; Hope, Sigmund Mongstad; Korsnes, Reinert; Hansen, Alex (Journal article; Peer reviewed, 2014-04-16)Fracturing and refreezing of sea ice in the Kara sea are investigated using complex network analysis. By going to the dual network, where the fractures are nodes and their intersections links, we gain access to topological ... -
Network topology of the desert rose
Hope, Sigmund Mongstad; Kundu, Sumanta; Roy, Chandreyee; Manna, S. S.; Hansen, Alex (Journal article; Peer reviewed, 2015-09-08)Desert roses are gypsum crystals that consist of intersecting disks. We determine their geometrical structure using computer assisted tomography. By mapping the geometrical structure onto a graph, the topology of the desert ... -
Topological impact of constrained fracture growth
Hope, Sigmund Mongstad; Davy, Philippe; Maillot, Julien; Le Goc, Romain; Hansen, Alex (Journal article; Peer reviewed, 2015-09-08)The topology of two discrete fracture network models is compared to investigate the impact of constrained fracture growth. In the Poissonian discrete fracture network model the fractures are assigned length, position and ... -
Topology of fracture networks
Andresen, Christian Andre; Hansen, Alex; Le Goc, Romain; Davy, Philippe; Hope, Sigmund Mongstad (Journal article; Peer reviewed, 2013)We propose a mapping from fracture systems consisting of intersecting fracture sheets in three dimensions to an abstract network consisting of nodes and links. This makes it possible to analyze fracture systems with the ... -
Topology of Fracture Networks
Hope, Sigmund Mongstad (Doctoral thesis at NTNU;2015:200, Doctoral thesis, 2015)This thesis is submitted as partial fulfilment of the requirements for the degree of philosophiae doctor. Methods from network science are applied to investigate the topology of fracture networks. The main focus is on ...
