Safety Factor
History of Safety Factor
The concept of safety factor has substantial history behind it. ...
Definition of Safety Factor
Safety Factor, also known as Factor of safety, is a multiplier applied to the calculated maximum stress to which a component will be subjected. Safety factor is the structural strength divided by the minimum structural strength required. The greater the safety factor, the lower the like hood of structural factor and the more stress cycles the structure can take. Small structures often have large safety factors because of the minimum gauge that can be crafted. Typically, for components whose failure could result in substantial financial loss, or serious injury or death, a safety factor of at least four (4) is used. Non-critical components generally have a safety factor of two (2). Safety factors are needed to account for imperfections in materials, flaws in assembly, material degradation, and unexpected stresses. ... The transition from engineering model to reality is usually facilitated by including a factor of safety in the design to accommodate uncertainty in material properties and the design process, the consequences of failure, risk to people, and degree of characterization of and control over the service environment.
