One-dimensional hole closure simulations have been performed to determine the effect of different constitutive models and assumed boundary conditions on the predicted rebound behavior of ocean sediments following penetrometer emplacement. It has been found that the type of yield criterion and the post yield behavior strongly influence the ability of sediment to reform a barrier behind a penetrometer. Elastic moduli, density, and overburden affect the rebound, but to a lesser degree than the yield criterion and post yielding response. Further, varying the imposed displacement constraints at assumed sediment boundaries can change the qualitative behavior of the cavity response.
