or expressed in terms of the side lengths:

(4.4)

The last equation can be rearranged for the unknown side length of the damaged RVE:

(4.5)

To calculate the relative density, it is required to calculate first the densities of the undamaged and the damaged RVE. The undamaged density is obtained as while the density of the damaged RVE is obtained with the side length a according to Eq. (4.5) as:

(4.6)

Thus, the relative density for this specific problem can be expressed as:

(4.7)
