ОСВРТ КОН ПРИМЕНА НА МАТЕМАТИЧКО – МОДЕЛИСКИ ПРИСТАПИ ПРИ ГЕОМЕХАНИЧКИ ЛАБОРАТОРИСКИ ИСПИТУВАЊА.

This paper provides an approach to the possible application of mathematical-model research in geomechanical tests. In addition, specific geomechanical laboratory tests were performed on a granite sample. After that for these tests, mathematical-model research was done in order to replace the modeling of physical-mechanical research. The laboratory material is crushed, classified and it is calculated the volume mass in the natural state and in the loose state (after crushing). Also, 3D model has been prepared with the reconstruction of images from the real model. Then, from this 3D model, using the DEM (Discrete Element Method), is made a model of particles (pieces), that replace the crushed material. On this model are analyzed some physical-mechanical characteristics. A comparative analysis defines the difference between actual laboratory and modeled results. [ABSTRACT FROM AUTHOR]
