Micro Abstract:
In this work presents a strategy to diminish the computational cost of a hierarchical (FE2) multi-scale computational homogenization approach for fracture problems is presented. Focusing on concepts as Reduced Order Modeling (ROM) based on the POD and optimal integration quadrature techniques, a hyper-reduced order modeling (HPROM) method is specifically derived. This model departs from the multi-scale framework developed in (Oliver/2015) for the numerical modeling of failure.
