Enter the original length (h) and the total deformation (w) into the calculator to determine the shear stress acting on a square object.

## Shear Strain Formula

The following formula is used to calculate shear strain.

y = w / h

- Where y is the shear strain
- w is the total deformation as seen in the illustration below
- h is the original length/height of the object

## Shear Strain Definition

A shear strain is defined as the deformation of an object due to shear stress.

## Shear Strain Example

How to calculate shear strain?

**First, measure the original length.**Measure the original length, often considered the height of a square object.

**Next, measure the deformation.**After a shear force has been applied to the object, measure the deformation.

**Finally, calculate the shear strain.**Calculate the shear strain by dividing the deformation by the original length.

## FAQ

**What is shear strain?**

Shear strain is a type of strain that is caused by a shear force or shear stress.

**What is shear stress?**

Shear stress is a stress caused two forces acting in opposing directions and opposing surfaces of an object.
