Optimization of Slopes Using the DEM & BEM

Popis výsledku v původním jazyce

Discrete element methods (DEM) are very often used in mechanics of granular media. They substitute the formulations for solving continuum. DEM enables researchers to find local discontinuities in displacements, propagation of cracks, etc., although the location of such disturbances is not known in advance. As is well known, the decisive points of instability in a material of the slope are damage states with localized stresses. On the other hand, the classical creep is also very important for the most kinds of soils. In this paper, the free hexagon element method is used in combination with nonlinear boundary elements. Mutual contacts obey Mohr-Coulomb law with excluded tension and the mechanical behavior of the hexagon elements themselves are ruled bytime-dependent strain. Considering the most of particles are of the same, or a similar shape, very powerful iterative procedures can be applied, and the computers relevant geometrical properties can be stored in the internal memory of
