Keywords: gravitational field, topography, tension-compression stresses, shear stresses, Mars
Аnnotation: It is shown that in calculations of the Martian interiors stresses, it is reasonable to apply the gravitational field data in the expansion of spherical harmonics up to the 90th order and degree (MRO120D and GMM-3 models). A comparative analysis of stresses based on these models is carried out. Stress estimates are calculated in the interiors of the planet under local topography structures, these areas are of interest to reveal the zones of possible marsquakes sources.
