# Ultimate Tensile Strength

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

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

$$\large{ UTS = \frac{ P_{max} }{ A } }$$

Where:

$$\large{ UTS }$$ = ultimate tensile stress

$$\large{ A }$$ = cross-section of origional area

$$\large{ P_{max} }$$ = maximum load
