Diurnal temperature variation as the source of the preferential direction of fractures on asteroids: Theoretical model for the case of Bennu

It has been shown that temperature cycles on airless bodies of our Solar System can cause damaging of surface materials. Nevertheless, propagation mechanisms in the case of space objects are still poorly understood. Present work combines a thermoelasticity model together with linear elastic fracture...
