Earlier the applicability of the local interaction model to the determination of the force and kinematic characteristics of sharp conical bodies is shown based on the data of the inverted experiments and numerical calculations in an axisymmetric formulation. Transient events associated with penetration. Laboratory investigation of the loading rate. Scaling effects in penetration: The usefulness of SPT results depends on the soil type, with fine-grained sands giving the most useful results, with coarser sands and silty sands giving reasonably useful results, and clays and gravelly soils yielding results which may be very poorly representative of the true soil conditions.
