Fisher distribution fracture sets
WebIn theory, the joint orientations of each fracture set can be determined by a Fisher distribution, Bingham distribution, bivariate normal distribution, or bivariate empirical distribution [40,42,43,44,45]. However, due to the complexity of the geological structure and investigation error, it is very difficult to determine a distribution that ... WebOur main results reveal: (1) NE/SW, E/W, and NW/SE fracture sets are the most recorded orientations along the virtual scanlines; (2) spacing distribution within NH shows that the clustering ...

A symmetric Fisher distribution … WebAug 1, 2024 · DarcyTools generates random fractures in space. This process is accomplished by utilizing independent uniform probability distributions for the location of fracture centers. The orientation of the fractures obeys the Fisher orientation distribution, where each fracture set is defined by mean pole trend, plunge, and concentration.
WebFracture loads and fracture modes were analyzed using two-way ANOVA and Fisher’s exact probability tests ( P ≤0.05). Results: SM0.3 design showed highest fracture loads with no significant difference compared to M and SMW designs ( P >0.05). SM0.5 design showed lower fracture loads compared to SMW and SWC designs. http://docs.itascacg.com/3dec700/common/dfn/doc/dfn_manual/dfn_commands/cmd_fracture_template.create.html
