    This paper describes the results from a centrifuge investigation into the rate dependence of T-bar and ball penetrometer resistance in kaolin. Four T-bar diameters and two ball diameters were installed in kaolin with overconsolidation ratios of 1, 2 and 5 at penetration velocities varying over five orders of magnitude. The penetration resistances are compared with the properties of kaolin as measured in element tests to assist in the development of a framework that describes this resistance over the full velocity range. Consistent trends emerge when the soil viscosity is assumed to affect the penetration resistance in both the partially drained and undrained conditions, enabling the dependence of the T-bar and ball resistances on diameter, velocity and soil characteristics to be quantified.
