We present a recently developed hyper-reduction technique called Empirically Corrected Cluster Cubature (E3C) and its application to two-scale elastoplasticity. The method identifies a reduced set of integration points through preliminary clustering and empirically corrects them through a cost function minimization. The approach is applied to a computationally homogenized elastoplastic material model.
