Dear RG users,
I would like to model fractures in 3D and integrate it into my model. Which may be Finite Element Method (FEM) based, Discrete Element Method (DEM) based or a hybrid (FDEM) based.
I am particularly interested in rock masses so in this case; modeling discontinuities. However, any suggestions that can be used to model fracture systems will be very much appreciated. If your suggestion is software based please tell the name of it.
Thank you,
Bekir SF
I hope the article titled:
3D numerical modelling of rock fracture with a hybrid finite and cohesive element method
By: Hongxiang Jiang and Deguang Meng
be helpful for you
Best wishes
Dear Bekir,
your problem can be simulated easily using PLAXIS software..in plaxis software jointed rock model is available..so it can be used to simulate the rock discontinuities.. also, you can use interface element b/w two rock elements to simulate the joint..the interface can be used only the point at which rock is discontinuous ..ok all the best in your research..
Dear Bekir Salih Firincioglu,
I recommend some papers:
Grenon M, Bruneau G, Kapinga Kalala I (2014) Quantifying the impact of small variations in fracture geometric characteristics on peak rock mass properties at a mining project using a coupled DFN-DEM approach. Comput Geotech. doi: 10.1016/j.compgeo.2014.01.010
Mahnaz Laghaei, et al. (2018) Numerical determination of deformability and strength of 3D fractured rock mass. International Journal of Rock Mechanics and Mining Sciences, 110, 246-256.
This can be done using RS3 Rocscience. But it is important to remember that the statistically processed parameters of cracks are not the same as the most dangerous ones. A single unfavorable combination (very far from the result of statistical processing) is enough to collapse the slope. This analysis can also be performed in the programs Rocscience (Dips and Swedge).
Thank you all for your answers. I will keep them in my mind.
Dear Luyu Wang
, How much programming skill do you need to implement such condition into an open source software? I practically do not have any skill to write such a code.Best Regards,
Bekir
