Enter the number of dislocations and the volume into the Calculator. The calculator will evaluate the Dislocation Density. 

Dislocation Density Formula

DLD = D / V


  • DLD is the Dislocation Density (dislocations/unit volume)
  • D is the number of dislocations
  • V is the volume

To calculate Dislocation Density, divide the number of dislocations by the total volume.

How to Calculate Dislocation Density?

The following steps outline how to calculate the Dislocation Density.

  1. First, determine the number of dislocations. 
  2. Next, determine the volume. 
  3. Next, gather the formula from above = DLD = D / V.
  4. Finally, calculate the Dislocation Density.
  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.

number of dislocations = 3.4

volume = 123
