Abstract

This paper presents a Novelty-based detection technique to identify core material properties of honeycombs and cellular structures. A numerical model (FE) representing full scale and/or reduced size of the cellular solid is used to generate transmissibilities between topological points at cells in different locations, with a statistical Gaussian distribution of the core material property target variable. The numerical set of transmissibilities is then used in a Novelty detection framework to find Euclidean and Mahalanobis distances from analogous data from a point excitation experimental test carried out with SLV.
