3D Stress Analysis for Tabular Ore Bodies
ExamineTAB is a three-dimensional displacement discontinuity program for calculating elastic stresses and displacements within tabular ore bodies due to staging of excavations. All excavations must lie on the same plane and be of the same height.
ExamineTAB provides an integrated graphical environment for data entry and visualization. A CAD based modeler allows for point and click geometry input and editing. Popup windows allow for easy entry and modification of model parameters.
The simple to use editing tools provide a convenient method for performing parametric studies. The graphical data interpreter provides a rich set of tools for the convenient display of model results. With ExamineTAB you can quickly create and mesh a model, perform a stress analysis, and interpret the results.
