| Abstract: | The discrete element method is a numerical method suitable for solving problems associated with jointed rock mass, while the Lagrangian element method is especially suitable for salving problems involving large strains. The fundamental principles of both the discrete and the Lagrangian element methods and the problems of choosing parameters are described in this paper. The application ranges of the methods in geomechanics are also discussed. |
