AbstractA nonlinear, finite element analysis has been carried out to investigate the influence of three-dimensional loading and geometry on deformation and failure of an artificial island. The results of plane-strain and three-dimensional computations are compared. Calculations indicate that plane- strain analysis does not always yield results on the safe side. Depending on the loading configuration, a three- dimensional analysis can predict larger deformations and smaller load-carrying capacity. When the ice load on an artifical island increases gradually, the principal stress axes rotate; the paths to failure are significantly different in plane-strain and three-dimensional analyses.
