« on: 20/07/2017 10:49:47 »For a solid elastic body at rest, after setting the equations for the force equilibium and the generalized Hooke's law, we have 3 differential equations, linking the displacements and its derivatives to the body forces.
When the body forces results only from a gravitational field, that displacements can be a measure of the tidal forces of the field.
