| CALC : Material : Stress 011 : True Stress And Strain From Engineering Stress And Strain : Calculator
Description : Calculate the true stress and strain from the engineering stress and strain.
Discussion : True stress and strain are measured relative to the stressed dimensions of the material.
Input Variables :
- εe = Engineering Strain
- σe = Engineering Stress
Output Variables :
- εt = True Strain
- σt = True Stress
Calculation :
σt = σe ( 1 + εe )
εt = log( 1 + εe )
