Abstract

Often times occasional events may cause significant displacement and corresponding stress strain damage to a structure. Using limited sets of measured data, expansion of real time data has been shown to provide accurate full field displacement results. This displacement data can be used in conjunction with the finite element model to identify full field dynamic stress-strain results. This approach is demonstrated for an analytical model to show the methodology proposed. Examples illustrating different configurations of measured data sets along with simulated noise are presented to illustrate the technique.
