Yield Strength

Written by Matt Milbury on . Posted in Pipe

Yield strength, abbreviated as \(\sigma\) (Greek symbol sigma), also known as yield stress, is the minimum stress that leads to permanent deformation of the material.

Yield Strength formula

\(\large{ \sigma = \frac{F}{A} }\)

Where:

\(\large{ \sigma }\) (Greek symbol sigma) = yield strength

\(\large{ A }\) = cross-section area

\(\large{ F }\) = force

Solve for:

\(\large{ A = \frac{F}{\sigma} }\)

\(\large{ F = \sigma \; A }\)
