Numerical Simulation of the Martian Stress Field Excluding Long-Wavelength Harmonics

A. V. Batov, Т. В. Гудкова

We present a numerical investigation of the stress field within Mars, focusing on the influence of shorter-wavelength topographic and gravitational components while deliberately omitting the contribution of long-wavelength harmonics. Calculations were carried out on a global 1° × 1° grid, using expansions …

Stress state of the Mars’ and Venus’ interior

Т. В. Гудкова, A. V. Batov

It is shown that most of the epicenters of marsquakes are located in the zones of extension and fairly large shear stresses associated with the deviation of Mars from hydrostatic equilibrium. Non-hydrostatic stresses in the interior of Venus are calculated for two …
