Ultimate Tensile Strength

Ultimate Tensile Strength Equation



$$ U.T.S = \sigma_{max} = \frac{P_{max}}{A_0} $$
where:

U.T.S   =   Ultime Tensile Strength   (Pa)

Pmax   =   Maximum Load   (N)

A0  =   Original cross-sectional area   (m²)

Equation Assumptions



  • The material composition is uniform.
  • Temperature and pressure are assumed to be constant.
  • Material is non-porous.
  • The material is pure/ideal.
