# How to Calculate and Solve for True Stress | The Calculator Encyclopedia The image above represents the true stress.

To compute for the true stress, two essential parameters are needed and these parameters are force (F) and instantaneous area (Ai).

The formula for calculating true stress:

σT = F / Ai

Where;
T = True Stress
F = Force
Ai = Instantaneous Area

Let’s solve an example;
Find the true stress when the instantaneous area is 60 with a force of 25.

This implies that;
F = Force = 25
Ai = Instantaneous Area = 60

σT = F / Ai
σT = 25 / 60
σT = 0.416

Therefore, the true stress is 0.416 Pa.

Calculating the Force when True Stress and Instantaneous Area is Given.

F = Ai x σT

Where;
F = Force
σT = True Stress
Ai = Instantaneous Area

Let’s solve an example;
Find the force when the instantaneous area is 30 with a true stress of 15.

This implies that;
σT = True Stress = 15
Ai = Instantaneous Area = 30

F = Ai x σT
F = 30 x 15
F = 450

Therefore, the force is 450.

Calculating the Instantaneous Area when True Stress and Force is Given.

Ai = F / σT

Where;
Ai = Instantaneous Area
F = Force
σT = True Stress

Let’s solve an example;
Find the instantaneous area when the force is 440 with a true stress of 22.

This implies that;
σT = True Stress = 22
F = Force = 440

Ai = F / σT
Ai = 440 / 22
Ai = 20

Therefore, the instantaneous area is 20.
