Reduced order models for material non‐linearities in FEM applications

Abstract: In this paper, an adaptive reduced order method for small strain elasto‐plasticity is discussed. This method works purely online, meaning no preliminary offline calculations have to be conducted. Using a GALERKIN projection, the high‐fidelity problem is reduced to a lower vector space. For this, the basis is extracted from an initial POD after the first few load steps of the simulation. Later on, POD is used again to check the relevance of new snapshots gained from the load stepping. Corrections of the basis ensure the best performance of the current basis.
