Equation for factor of safety

WebFactor of Safety = Ultimate Stress/Permissible Stress F.O.S = U/P What is Factor of Safety? The ratio of ultimate stress to permissible stress is called a factor of safety. the maximum stress to which any member is designed is much less than the ultimate stress, and this stress is called permissible stress How to Calculate Factor of safety? WebNov 7, 2012 · A Factor of Safety is then applied to those loads, to determine Design Ultimate Loads (DUL), still in terms of loads and specific to each structure. This is the load case used to design the structure. Typically the Factor of Safety is 1.5. Each part is then subject to analysis to determine the maximum STRESS at DUL (not DLL).
