Abstract
In a previous study [1] we estimat-ed the necessary spin rate of a mined asteroid hosting a cylindrical space station with artificial gravity and estimated its required material strength deploying two simplified analytical models. Applying these models to fictitious, yet realistic rocky near-Earth asteroids resulted in material strengths comparable to tensile and shear strengths of basalt [1]. Here we present re-sults of a series of smooth particle hydrodynamics (SPH) simulations of a typical configuration with var-ying porosity of the parent body and compare the SPH results which are based on solid body continuum me-chanics to the analytical model predictions.
