Normal strain calculator

Normal strain, also known as axial strain, is a measure of the deformation or change in size of a material along the direction of the applied force or stress. It is defined as the ratio of the change in length ($\Delta L$) to the original length ($L$) of the material. The formula for normal strain (ϵaxial​) in full SI units is given by:

​

where:

• axialϵaxial​ is the normal strain (dimensionless),
• $\Delta L$ is the change in length (in meters, m),
• $L$ is the original length (in meters, m).
