About this calculator

How it works

Yield strength is the engineering stress where a material begins to deform plastically. It is often determined from a tensile test or proof stress method.

Formulas

Formulas used

Yield strength

sigma_y = Fy / A0

Worked example

Example calculation

Yield strength

sigma_y = 35 kN / 100 mm2 = 350 MPa

Reference

What the results mean

Yield strength

Stress associated with the start of permanent deformation.

Factor of safety context

Design stress is often compared with yield strength using a safety factor.

Assumptions and limits

Before using the result

Inputs are treated as representative engineering values from a test, datasheet, or early design estimate.
Material properties vary with grade, heat treatment, temperature, strain rate, moisture, manufacturing route, and test method.
Use verified material data, applicable standards, safety factors, and qualified engineering judgement for final design or failure analysis.
