A flat-plate penetrometer, similar to the flat-dilatometer, has been constructed and used in a series of laboratory experiments to estimate the shear modulus of cohesionless soils under repetitive loading conditions. Tests were performed on sand specimens prepared at different relative densities and loaded vertically to simulate the overburden pressure at different depths. Results indicate, despite penetration disturbance, a reasonable agreement between the shear modulus values determined using the flat-plate penetrometer data and the empirical formulations published in the literature.
