Quantification of non-homogeneous interval uncertainty based on scatter in modal properties
2017
Procedia Engineering
The objective of this work is to develop and validate a methodology for the identification of intra-variability based on the Interval Field concept, with a specific focus on dynamic FE models. The principal idea is to find a solution to an inverse problem, where the variability on the output side of the model (i.e., the eigenfrequencies) is known from measurement data, but the spatial uncertainty on the input parameters is unknown. Specifically, focus is placed on the identification of the
