Abstract

Both static and dynamic penetration tests are widely used to conduct soil investigation practice. Particle crushability has been known to greatly affect the responses of penetration tests. On the other hand, the physical property of granular materials – surface roughness – exhibits considerable influence on crushability. The virtual calibration chamber (VCC) technique, based on the Discrete Element Method (DEM), is used to investigate the effect of particle crushability and roughness on both static and dynamic penetration test responses. In static tests particle crushing reduces tip resistance, and roughness enhances this effect as rough particles crush more than smooth ones. The main effects of roughness and crushability on dynamic responses lie in the track of dynamic penetrograms. The analysis confirms a good correlation between an equivalent dynamic resistance and the static tip resistance.
