ABSTRACT

For this study, a large deformation finite element approach based on the commercial finite element software ABAQUS (Dassault Systèmes, 2007) was developed, following a similar approach to that described by Wang et al. (2010). The ‘remeshing and interpolation technique with small strain’ (RITSS: Hu & Randolph 1998) method was used, with the original shear strength of the soil modified to account for any increase due to high strain rates and any decrease due to softening (through the accumulation of plastic strain). After the results had been validated by comparing with existing centrifuge test data, a parametric study was undertaken over a wide range of soil properties.
