Description
| - Rock masses with relatively high concentration of discontinuities or joints are considered. Being aware of limitations of various averaging techniques such as the self consistent orMori-Tanaka methods in providing reliable estimates of generally nonlinear macroscopic response of jointed rock masses, the paper introduces a notion of statistically equivalent periodic unit cell (SEPUC). Such a unit cell contains, in order to reduce the problem complexity, of the orders of magnitude less number of joints in comparison with the actual material system. In analogy with two-phase composites, the SEPUC is expected to be found in a statistical sense by matching suitable microstructure descriptors of both the actual microstructure and periodic one. A possibility of using the second order intensity function as a informative descriptor of the cracks distribution is investigated and possible improvements, although without computational support, are proposed.
