dc.description.abstract | There are two aspects in this study: cylinder penetrations and XBP (Expendable
Bottom Penetrometer) interpretations. The cylinder studies firstly investigate the
relationship between the soil resisting force and penetration depth by a series of rateindependent
finite element analyses of pre-embedded penetration depths, and validate
the results by upper and lower bound solutions from classical plasticity theory.
Furthermore, strain rate effects are modeled by finite element simulations within a
framework of rate-dependent plasticity. With all forces acting on the cylinder estimated,
penetration depths are predicted from simple equations of motion for a single particle.
Comparisons to experimental results show reasonable agreement between model
predictions and measurements.
The XBP studies follow the same methodology in investigating the soil shearing
resistance as a function of penetration depth and velocity by finite element analyses.
With the measurements of time decelerations during penetration of the XBP, sediment
shear strength profile is inferred from a single particle kinetic model. The predictions
compare favorably with experimental measurements by vane shear tests. | en |
