Multiscale computational homogenization methods with a gradient enhanced scheme based on the discontinuous Galerkin formulation
A strain-gradient formulation is developed using a discontinous Galerkin framework. The resulting one-field formulation can easily be implemented in existing software. This formulation is used for second-order multiscale computational homogenizations. The micro and macro-scale problems consider finite strains. Size effects in heterogeneous elastoplastic materials is can be studied.
