The image above represents partial dislocation separation.

To compute for partial dislocation separation, four essential parameters are needed and these parameters are **Shear Modulus (G), Burger Vector (b _{2}), Burger Vector (b_{3}) **and

**Stacking Fault Energy (γ).**

The formula for calculating partial dislocation separation:

d = ^{Gb2b3} / _{2πγ}

Where:

d = Partial Dislocation Separation

G = Shear Modulus

b_{2} and b_{3} = Burger Vectors

γ = Stacking Fault Energy

Let’s solve an example;

Find the partial dislocation separation when the shear modulus is 4. the burger vectors is 8 and 10, the stacking fault energy is 14.

This implies that;

G = Shear Modulus = 4

b_{2} and b_{3} = Burger Vectors = 8 and 10

γ = Stacking Fault Energy = 14

d = ^{Gb2b3} / _{2πγ}

d = ^{(4)(8)(10)} / _{2π(14)}

d = ^{320} / _{87.96}

d = 3.64

Therefore, the **partial dislocation separation **is **3.64 m.**
