... (e.g. joint elements in FEM), they are only applicable for less jointed rock mass where little displacement is expected [7, 8]. To deal with inherent discontinuities in the rock mass and possible rupture in the intact rock, discontinuum methods prove to be best till date. Discontinuum methods are based...
