UDEC 6.0 – itasca
The Universal Distinct Element Code (UDEC) is a two-dimensional numerical software that simulates the quasi-static or dynamic response to loading of media containing multiple, intersecting joint structures.
The discontinuous medium is represented as an assemblage of discrete blocks while the discontinuities are treated as boundary conditions between blocks. Large displacements along discontinuities and rotations of blocks can occur. UDEC utilizes an explicit solution scheme that can model complex, non-linear behaviors.
Because it is not limited to a particular type of problem or initial condition, UDEC may be applied to a wide variety of physical behaviors or any case where an understanding of the two-dimensional response of such structures is needed. UDEC is capable of simulating and is used for a wide range of engineering and scientific analyzes including:
Stability analysis of jointed rock slopes;
Deep underground excavations;
Ground support reinforcement;
Integrity of radioactive waste storage facilities;
Natural gas storage in rock caverns;
Dams and dam foundations;
Fluid flow though jointed rock;
Solid mechanics and micro-damage of intact materials; and
Stability of masonry structures.
