Abstract : A numerical approach for analyzing rockbursting phenomenon as a surface instability has been developed. Computer program modules that can be incorporated into general purpose nonlinear finite element codes have been created. The numerical approach has been successfully applied for a simple case of the wedge test. Contents--Numerical Method for Assessing Surface Instability; Numerical Results on Surface Instability of the Wedge Test; Influence of Material Modeling on Surface Instability; Influence of Non-Uniform Stress Field on Surface Instability; Conclusions and Recommendations; Biot's Approach to Surface Instability; Analytical Solution of the Response of an Hypo-Elastic Solid Subjected to Finite Plane Strain Compression.
