How to Calculate and Solve for Shear Strain Rate | Shearing Processes

Last Updated on March 5, 2021

The image above represents shear strain rate.

To compute for shear strain rate, two essential parameters are needed and these parameters are Velocity of Shear Zone (v_s) and Thickness of Shear Zone (t_s).

The formula for calculating shear strain rate:

S^* = ^v_s / _ts

Where:

S^* = Shear Strain Rate
v_s = Velocity of Shear Zone
t_s = Thickness of Shear Zone

Let’s solve an example;
Find the shear strain rate when the velocity of shear zone is 24 and the thickness of shear zone is 12.

This implies that;

v_s = Velocity of Shear Zone = 24
t_s = Thickness of Shear Zone = 12

S^* = ^v_s / _ts
S^* = ²⁴ / ₁₂
S^* = 2

Therefore, the shear strain rate is 2 Hz.

Calculating the Velocity of Shear Zone when the Shear Strain Rate and the Thickness of Shear Zone is Given.

v_s = S^*x t_s

Where;

v_s = Velocity of Shear Zone
S^* = Shear Strain Rate
t_s = Thickness of Shear Zone

Let’s solve an example;
Find the velocity of shear zone when the shear strain rate is 10 and the thickness of shear zone is 14.

This implies that;

S^* = Shear Strain Rate = 10
t_s = Thickness of Shear Zone = 14

v_s = S^*x t_s
v_s = 10 x 14
v_s = 140

Therefore, the velocity of shear zone is 140.

Calculating the Thickness of Shear Zone when the Shear Strain Rate and the Velocity of Shear Zone is Given.

t_s  = ^v_s / _S^*

Where;

t_s = Thickness of Shear Zone
S^* = Shear Strain Rate
v_s = Velocity of Shear Zone

Let’s solve an example;
Find the thickness of shear zone when the shear strain rate is 20 and the velocity of shear zone is 180.

This implies that;

S^* = Shear Strain Rate = 20
v_s = Velocity of Shear Zone = 180

t_s  = ^v_s / _S^*
t_s  = ¹⁸⁰ / ₂₀
t_s  = 9

Therefore, the thickness of shear zone is 9.
