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.

Famous quotes containing the words yield, ultimate and/or calculations:
“The field of the poor may yield much food, but it is swept away through injustice.”
—Bible: Hebrew, Proverbs 13:23.
“Only with the ultimate knowledge of all things will man have come to know himself. For things are but the boundaries of man.”
