Aulova, Alexandra; Rogelj Ritonja, Alenka; Emri, Igor Approximate model for geometrical complex structures Many engineering structures are made of composite materials or metal foam. To simulate the deformational behaviour of these structures often requires a high number of discretisation elements. This in turn yields a very large system of linear equations that are extremely time and memory consuming or practically impossible to solve. It is therefore desirable to find an approach to overcome this obstacle.

For linear solids which obey the Hooke's law, the material parameters determination from measurements is being examined. 2015 32nd Danubia-Adria Symposium on advances in experimental mechanics Starý Smokovec, Slovakia 22.09.2016 25.09.2016 2016-04-05 OPUS4-35629 Zeitschriftenartikel Wu, Cheng-Chieh; Weisbrich, S.; Neitzel, F. Nicoletto, G.; Pastrama, S. D.; Emri, I. Inverse finite element adjustment of material parameters from integrated analysis of displacement field measurement The determination of material parameters from displacement field measurement is being examined for linear elastic solid. A frequently used approach to compute material constants can be found in many studies. Even though they presented the approach in many different variations, but in the end they are essentially based on the same algorithm: Parameters are iteratively tuned until the computed results are in accordance with the measurements. The main drawback of this approach is that mainly commercial software is used that hinders us to investigate its inner evaluation process. This leads to the question, how the results from this commercial software can be trusted. On the contrary to these debatable approaches, we present a method that inverts the procedure of finite element method by using the most general model for a least-squares adjustment - the GAUSS-HELMERT Model.
