Enter the design stress and factor of safety into the calculator to determine the estimated yield strength of the material.

## Yield Strength Formula

The following formula can be used to estimate a yield strength

Y_{s} = f_{s} * D_{s}

- Where Ys is the yield strength
- fs is the safety factor
- Ds is the design stress

This value is only an estimate. True yield strength can only be determined through experimental processes.

## Yield Strength Definition

A yield strength is defined as the maximum amount of stress a material can take without causing permanent deformation.

## Yield Strength Example

How to calculate a yield strength?

**First, determined the safety factor.**Determine the safety factor of the design.

**Next, determine the design stress.**Determine the maximum design stress.

**Finally, calculate the yield strength.**Calculate the yield strength using the formula above.

## FAQ

**What is a yield strength?**

A yield strength is the maximum amount of stress or force that can be applied to a material or object without causing permanent change to the shape. In other words, at which point does the material surpass it’s elastic limit.

**What is a design stress?**

A design stress is the maximum surface stress of a simple load.

**What is a safety factor?**

A safety factor is a factor that is used in engineering design to determine the safe operating limits or maximum stress a structure should be able to withstand.
