STRESSES AND STRAINS IN THE INTERIOR OF A NON-EVOLUTIVE PLANET

Abstract

The case of a hypothetical planet with an initial structure and density distribution similar to the present earth, is analyzed.Bullen’s and Gutenberg’s values for the densities and velocities in the interior are assumed, them gravity force is "turned on". Values for the radial and tangential stresses is of the order of 170.000 atmospheres near the surface and 600,000 atmospheres near the core boundary. The pressure at the center of the planet, assuming a liquid core, would be about 14 million atmospheres. The influence of the assumed method of formation of the earth on the stress-strain distribution is discussed.
