"The Remaining Strength Factor (RSF) shall be calculated as: RSF = (1 - (Area_removed / Area_original)) / (1 - (1/M) Where M is the Folias factor (bulging factor). Acceptance is achieved if RSF > RSF_allowable (typically 0.9)."
uses pre-calculated charts and formulas (like the "remaining strength factor" charts). Tier 2 uses analytical formulas derived from fracture mechanics and limit load analysis. Tier 3 requires non-linear finite element analysis (FEA) and probabilistic fracture mechanics—usually performed by a specialist. api 579
