Margin of Safety is the common method for design criteria. It is defined MS = P u /P − 1. For example, to achieve a factor of safety of 4, the allowable stress in an AISI 1018 steel component can be calculated to be F = U T S / F S {\displaystyle F=UTS/FS} = 440/4 = 110 MPa, or F {\displaystyle F} = 110×10 6 N/m 2 .
