Map3D Fault-Slip - elastic rock mass and fully plastic fault-slip stress analysis.
Includes the 3D CAD modeller, the results viewer and the GIS visual database.
The stress analysis utilizes the BEM (boundary element method) and has many features:
- the ability to analyze very large problem sizes (one million degrees of freedom)
- full 3D complex excavation shapes
- multiple elastic zones with different moduli (stiff dykes or soft ore)
- zones with different pre-mining stress states
- tabular mining with yielding pillars
- discrete non-planar fault planes that slip and dilate elasto-visco-plastically (including creep)
- cracks and fractures can be readily simulated including energy release rate and stress intensity calculations
- multiple mining steps are required to consider effects such as backfill placement or crack propagation
- automatic Boolean intersections allows for excavations, faults and fractures to cross and overlap
- automated discretization
A demonstration version of Map3D Fault-Slip is available at no charge. All features are available except the user is only permitted to run small size problems. This version is extremely useful for teaching the fundamentals of modelling, visualization and 3D CAD.Read More ...
Map3Di Integrated Seismicity - superimpose external field loading effects into the stress analysis.
Includes all capabilities from Map3D Fault-Slip and adds field loading effects. The field loading effects can be imported from any database of thermal heating, fluid pressure, non-linear behaviour and deformations indicated by seismicity. These effects can be used to characterize 2D and 3D geologic features, accommodate changing lithology and incorporate seismic loading effects into the stress analysis.Read More ...
Map3D Thermal-Fluid flow
Map3D Thermal-Fluid Flow - thermal stress - fluid flow analysis.
Includes all capabilities from Map3D Fault-Slip and adds simultaneous solution of steady state thermal stress - fluid flow. The program is set up so that the user need only specify the temperature/head boundary conditions, then the thermal stress problem is solved simultaneously. This feature is useful for simulation of heating/cooling effects and drained/undrained response.Read More ...
Map3D Non-Linear - non-linear rock mass response.
Includes all capabilities from Map3D Fault-Slip and adds the capability for the 3D rock mass to yield to loads that exceed the rock strength, and deform non-linearly to dissipate the excess stresses. This feature is useful for simulation of thick seams, over-stressed pillars, abutments, backfill and creep response. This formulation solves the non-linear problem on the surface of the boundary elements and interpolates these effects between these boundaries. This represents a first approximation to inelastic modelling that boasts the advantage of large problem sizes and very fast execution speeds.Read More ...
Map3D Visco-Plastic - 3D elasto-visco-plastic rock mass response. This version is now available commercially.
Includes all capabilities from Map3D Fault-Slip and adds the capability for the 3D rock mass to behave elasto-visco-plastically. This model features a full solution of the non-associated incremental plasticity equations and adds the capability for the 3D rock mass to yield to loads that exceed the rock strength, and deform non-linearly to dissipate the excess stresses. This feature is useful for simulation of thick seams, over-stressed pillars, abutments, backfill and creep response. This formulation solves the plastic problem throughout specified zones in the rock mass.Read More ... Applications
