ABSTRACT

A new state-of-the art methodology named as inverse Finite Element Method (iFEM), which certainly satisfies the necessities of SHM procedure, was developed by Tessler & Spangler (2003, 2005). iFEM algorithm reconstructs the structural deformations from experimentally measured strains based on the minimization of a weightedleast-square functional. Unlike other inverse methods, iFEM methodology possesses a general applicability to complex structures subjected to complicated boundary conditions in real-time (Tessler & Spangler 2005). iFEM framework is precise, powerful and sufficiently fast for real-time applications of any type of static and dynamic loadings, as well as a wide range of elastic materials since only strain-displacement relationship is used in the formulation (Gherlone et al. 2012, 2014).
