Description
A novel hyper-reduction technique is proposed and applied to nonlinear magnetostatic and mechanical computational homogenization. The method combines the ideas of microstructural clustering with the empirical identification of a reduced set of integration points. The macroscopic magnetic response (2D) is hardly distinguishable from the finite element results already for 12 integration points at a phase contrast of 1000 for a porous microstructure. Similar values have been found for mechanics.
