Enter the original axial length (in) and the axial strain (in/in) into the Axial Deformation Calculator. The calculator will evaluate the Axial Deformation. 

Axial Deformation Formula

The following two example problems outline the steps and information needed to calculate the Axial Deformation.

AD = ε * L


  • AD is the Axial Deformation (in)
  • ε is the original axial length (in) 
  • L is the axial strain (in/in) 

To calculate the axial deformation, multiply the original axial length by the axial strain.

How to Calculate Axial Deformation?

The following steps outline how to calculate the Axial Deformation.

  1. First, determine the original axial length (in). 
  2. Next, determine the axial strain (in/in). 
  3. Next, gather the formula from above = AD = ε * L.
  4. Finally, calculate the Axial Deformation.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

original axial length (in) = .75

axial strain (in/in) = 3

AD = ε * L = ?
