Abstract

A finite element formulation developed by Belytschko and his coworkers [1] is used to examine localized deformation as it exists for laboratory specimens of compressible Chicago clays. The element is based on an assumed strain formulation wherein localized and non-localized zones are embedded into an element when material based bifurcation is detected. A plane strain compression test of a natural clay specimen in which deformations localized into a single shear band during undrained shear is simulated using this element. Localization is initiated by imposing a non-uniform applied displacement consistent with that measured experimentally. Results indicate that to insure localization to a single band, considerations must be made for non-uniformities developed during the consolidation phase.
