Zhu and Lee present a closed-form explicit LEM solution that avoids iterative procedures by expressing FOS directly as a function of geometry, unit weight and shear-strength parameters. They show excellent agreement with rigorous methods for circular failures and provide guidance for rapid hand checks.
