Bishop Simplified Method of Analysis - Circular Failure Surface
---------------------------------------------------------------
Critical Failure Surface Search using Multiple Circle Generation Techniques
Factor of Safety for initial failure surface approximation: 3.472
There were: 124999 successful analyses from a total of 125001 trial surfaces
2 analyses terminated due to unacceptable geometry
Critical (minimum)Factor of Safety: 3.04
