Abstract
A framework is developed within the context of the displacement finite element method for applying periodic boundary conditions to uni-period basic cells under the influence of applied macroscopically homogeneous stresses. The resulting approach supplements the more common strain-controlled method which is also presented and which relies on an additive decomposition of the displacement field into linear (imposed) and periodic (unknown) contributions. As implemented here, the stress-controlled method employs a penalty formulation to insure that the displacement solution satisfies the linearperiodic decomposition. The performance of both the stress and strain driven methods are demonstrated and assessed on a complete set of homogenization computations for an elasto-plastic composite.
