Micro Abstract:
In this work, the first aim is to solve the task of two-scale homogenization of nonlinear materials for large deformations. We propose a model with a reduced basis for the deformation gradient. The accuracy of the predictions is evaluated online. The main benefit of this approach is the reduction of both CPU time and memory requirements. It also opens opportunities for generalization and further acceleration which are also discussed, e.g. data-driven techniques.
