For the case of zero body forces, show that by using the vector identity (1.8.5) 9 Naviers

Question:

For the case of zero body forces, show that by using the vector identity (1.8.5)₉ Navier’s equation can be written as:

Using repeated differential operations on this result, show that the displacement vector is
biharmonic. Furthermore, because the stress and strain are linear combinations of first derivatives
of the displacement, they too will be biharmonic.

Equation 1.8.5
