ITASCA 3DEC 4.0
3DEC (3-Dimensional Distinct Element Code) is the three-dimensional extension of Itasca‘s two-dimensional code UDEC. It is specifically designed for simulating either the quasi-static or dynamic response to loading of rock media containing multiple, intersecting joint structures. Main Features Simulation of large displacements (slip and opening) along distinct surfaces in a discontinuous medium Discontinuous medium treated as an assemblage of discrete polyhedra Discontinuities treated as boundary conditions between blocks Relative motion along discontinuities governed by linear and non-linear force-displacement relations for movement in both the normal and shear directions Explicit solution scheme, giving a stable solution to unstable physical processes Rigid or deformable blocks Library of material models for deformable blocks and for discontinuities Null blocks for excavation and nonlinear material...
