Yield & Ultimate Calculations
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 plastically deform. The ultimate calculation will determine the safety factor until failure. On brittle materials these values are often so close as to be indistinguishable, so is it usually acceptable to only calculate the ultimate safety factor.

“Time is here and you’ll go his way.
Your lung is waiting in the death market.
Your face beside me will grow indifferent.
Darling, you will yield up your belly and be
cored like an apple.”
