How to Calculate and Solve for True Stress – True Strain In Plastic Region | Mechanical Properties

The true stress – true strain in plastic region is represented by the image below. To calculate true stress – true strain in plastic region, three essential parameters are needed and these parameters are True Strain (εT), Constant (k) and Constant (n).

The formula for calculating true stress – true strain in plastic region:

σT = kεTn

Where:

σT = True Stress – True Strain in Plastic Region
εT = True Strain
k, n = Constants

Given an example;
Find the true stress when the true strain is 2, the constant is 5 and the constant is 10.

This implies that;

εT = True Strain
k = Constant
n = Constant

σT = kεTn
σT = 5(2)10
That is, σT = 5(1024)
σT = 5120

Therefore, the true stress is 5120 Pa.
