Ultimate Tensile Strength

Ultimate tensile strength, abbreviated as UTS, also called tensile strength or ultimate strength, is the maximum stress a material can resist before it starts to elongate.

 

Ultimate Tensile Strength formula

\(\large{ UTS = \frac{ F }{ A_c } }\)

Where:

Units	English	Metric
\(\large{ UTS }\) = ultimate tensile stress	\(\large{ \frac{lbf}{in^2} }\)	\(\large{ Pa }\)
\(\large{ A_c }\) = area cross-section of material	\(\large{ in^2 }\)	\(\large{ mm^2 }\)
\(\large{ F }\) = force or maximum load	\(\large{ lbf }\)	\(\large{ N }\)
