Navier Equations in Cylindrical and Spherical Coordinates 23?
In spherical coordinates, with u nUQ,u,p denoting the displacement components in
(r, $, (f>) direction, Hooke's law take the form of [See Sect. 2D3 for components of
V/,Vu and divu in spherical coordinates]
where
and the Navier's equations of motion are
