How to Calculate and Solve for Glide Shear | Fracture Mechanics

Last Updated on March 8, 2021

The image above represents glide shear.

To compute for glide shear, two essential parameters are needed and these parameters are Stacking Fault Energy (γ) and Varying Grain Constant (M’).

The formula for calculating glide shear:

E = ^γ / _M’

Where:

E = Glide Shear
γ = Stacking Fault Energy
M’ = Varying Grain Constant

Let’s solve an example;
Find the glide shear when the stacking fault energy is 18 and the varying grain constant is 2.

This implies that;

γ = Stacking Fault Energy = 18
M’ = Varying Grain Constant = 2

E = ^γ / _M’
E = ¹⁸ / ₂
E = 9

Therefore, the glide shear is 9 Pa.

Calculating the Stacking Fault Energy when the Glide Shear and the Varying Grain Constant is Given.

γ = E x M’

Where;

γ = Stacking Fault Energy
E = Glide Shear
M’ = Varying Grain Constant

Let’s solve an example;
Find the stacking fault energy when the glide shear is 14 and the varying grain constant is 8.

This implies that;

E = Glide Shear = 14
M’ = Varying Grain Constant = 8

γ = E x M’
γ = 14 x 8
γ = 112

Therefore, the stacking fault energy is 112.

Calculating the Varying Grain Constant when the Glide Shear and the Stacking Fault Energy is Given.

M’ = ^γ / _E

Where;

M’ = Varying Grain Constant
E = Glide Shear
γ = Stacking Fault Energy

Let’s solve an example;
Find the varying grain constant when the glide shear is 10 and the stacking fault energy is 40.

This implies that;

E = Glide Shear = 10
γ = Stacking Fault Energy = 40

M’ = ^γ / _E
M’ = ⁴⁰ / ₁₀
M’ = 4

Therefore, the varying grain constant is 4.
