Strength and energy consumption of inherently anisotropic rocks at failure [PDF]
, 2021 Using a discrete-element approach and a bonding interaction law, we model and test crushable inherently anisotropic structures reminiscent of the layering found in sedimentary and metamorphic rocks. By systematically modifying the level of inherent anisotropy, we characterize the evolution of the failure strength of circular rock samples discretized ...

Seasonal melting and the formation of sedimentary rocks on Mars, with predictions for the Gale Crater mound [PDF]
, 2012 A model for the formation and distribution of sedimentary rocks on Mars is proposed. The rate-limiting step is supply of liquid water from seasonal melting of snow or ice. The model is run for a O(10^2) mbar pure CO2 atmosphere, dusty snow, and solar luminosity reduced by 23%.
