Numerical simulation of the breakout process of an object at the ocean bottom

Abstract

This paper presents a numerical model to simulate the breakout process of an object at the ocean bottom. In the present model, a tiny gap (its initial width can be zero) is assumed during the pullout process. The fluid motion in the gap is assumed to be creeping flow. The seabed is assumed to be a linear elastic porous medium in which Darcy's law is valid. The results from the present model are compared to those from Mei et al. (1985) and they are found to agree well. © 2005 Taylor & Francis Group.
