The image above represents elongation potential of twin deformation.

To compute for elongation potential of twin deformation, two essential parameters are needed and these parameters are **Distance between the 2 Slip Planes (S) **and **Angle of Deformation (x).**

The formula for calculating elongation potential of twin deformation:

l’/l = (1 + Stanx)^{0.5}

Where:

l’/l = Elongation Potential of Twin Deformation

S = Distance between the 2 Slip Planes

x = Angle of Deformation

Let’s solve an example;

Find the elongation potential of twin deformation when the distance between the 2 slip planes is 24 and the angle of deformation is 12°.

This implies that;

S = Distance between the 2 Slip Planes = 24

x = Angle of Deformation = 12°

l’/l = (1 + Stanx)^{0.5}

l’/l = (1 + 24tan(12°))^{0.5}

l’/l = (1 + 24(0.213))^{0.5}

l’/l = (1 + 5.101)^{0.5}

l’/l = (6.101)^{0.5}

l’/l = 2.470

Therefore, the **elongation potential of twin deformation **is **2.470.**
