The three dimensional modeling will be released soon and more feature will be added soon. I also added a feature to model nonliner behavior of joint closure which is explained in detail in Mehranpour and Kulatilake (2017). The paper will look at systems for triaxial tests, the stages of a triaxial test, some of the theory behind triaxial tests and also automation of the test process. This includes why the test is performed and how it is performed. This pack is named 'Joint' and in the following version you can find the direct shear test and the uniaxial compression test for two dimensional modeling. This blog is designed to give a brief introduction to the theory of triaxial testing for a technician new to this test. In the following link you can find the developed FISHtank to model these tests in which more than 3,000 fish code lines are added or changed. One reason can be the shortcoming of the FISHtank in proposing the direct shear test and the uniaxial compression test on a joint plane. So far, limited efforts have been made on the calibration, and modeling of the SJCM. In SRM, discontinuities are generated by the Discrete Fracture Network (DFN) method. Therefore, block breakage as well as joint sliding can be considered. In this approach intact rock is modeled by the Bonded Particle Models (BPMs), and discontinuities are modeled by the Smooth-Joint Contact Model (SJCM).
#FLAC3D FISH CODE OF TRIAXIAL TEST SOFTWARE#
Introducing the Synthetic Rock Mass (SRM) approach in PFC has increased the power of this software to model the mechanical behavior of jointed rock masses. I should mention that these codes are based on the FISHtank and I developed them for other tests or models. Therefore in this part I would like to share some of my codes which I think could be useful for other researchers. However these supporting codes are not comprehensive. In order to simplify this condition ITASCA prepares FISHtank to support some common rock mechanics tests and makes an easier way to calibrate the micro properties that should be defined to get the appropriate macro properties. Thus for each test or each model specific codes should be written. Particles can have contact with adjacent particles or walls and force-displacement law acts at contacts. In this method particles are assumed as rigid and Newton's second law controls the interactions between the particles. The DEM method was introduced by Cundall (1971) and developed for granular material by Cundall and Strack (1979). PFC is a Distinct Element Method based software which uses spherical or disk elements to represent particles.
