Abstract

This work demonstrates novel methods for the stabilized enforcement of constraints associated with un-gridded interfaces, using enriched finite element methods for mechanics problems. Traditional methods such as penalty enforcement can be shown to yield oscillations in fluxes on interfaces. This method is based on a classical approach, Nitsche's method, and we have particular interest in study of suitable techniques for computing the Nitsche parameter. © CIMNE, 2007.
