  • Modelling of soil shearing behaviour under wheeled or tracked vehicles requires the knowledge of three soil properties: cohesion, angle of i nternal friction, and shear modulus. For lightweight robots it is necessary to characterize the soil for small normal stress (<15kPa) while most of the data collected in the literature regards higher stress testing conditions. Soil failure at l ow stress may diverge from Mohr-Coulomb envelope invalidating the fundamental assumptions behind classical… CONTINUE READING
