      A novel model-order reduction technique for the solution of the fine-scale equilibrium problem appearing in computational homogenization is presented. The reduced set of empirical shape functions is obtained using a ...

    • Multiscale formulation for material failure accounting for cohesive cracks at the macro and micro scales 

      Toro, Sebastian; Sánchez, Pablo J.; Blanco, Pedro J.; de Souza Neto, E.; Huespe, Alfredo Edmundo; Feijóo, R.A. (2016-01)
