For ductile materials (e.g. most metals), it is often required that the factor of safety be checked against both yield and ultimate strengths. The yield calculation will determine the safety factor until the part starts to deform plastically. The ultimate calculation will determine the safety factor until failure. On … See more In engineering, a factor of safety (FoS), also known as (and used interchangeably with) safety factor (SF), expresses how much stronger a system is than it needs to be for an intended load. Safety factors are often calculated … See more Appropriate design factors are based on several considerations, such as the accuracy of predictions on the imposed loads, … See more • Lalanne, C., Specification Development - 2nd Ed., ISTE-Wiley, 2009 See more There are two definitions for the factor of safety (FoS): • The ratio of a structure's absolute strength (structural … See more There are several ways to compare the factor of safety for structures.
