This paper shows a numerical replication of a laboratory-scale free fall cone 

penetrometer test of marine clay. The numerical simulation involves large deformations and 

considers the destructuration of clay, strain rate effects, and non-linear material behaviour. The 

numerical simulation well replicates the laboratory experiment captured on a high-speed 

camera. The penetration process is replicated accurately in time, and the depth of the penetration 

corresponds to that obtained in an experiment. The simulation results indicate that the numerical 

framework implemented in Uintah software, consisting of an advanced soil model and the 

Generalized Interpolation Material Point Method, is well-suited for replication of the dynamic 

penetration process in soft and sensitive marine clay.
