    Abstract

    This paper reports the results from 3D dynamic large deformation FE (LDFE) analyses of a 4-fin torpedo anchor installing through lightly overconsolidated calcareous silt. Analyses were performed simulating centrifuge test data for validation. A parametric study was then undertaken, exploring a range of impact velocity, in an attempt to provide an expression for estimating anchor embedment depth in the field. The 3D LDFE analyses were carried out using a Coupled Eulerian-Lagrangian (CEL) approach in the commercial FE package Abaqus/Explicit.
