Abstract
We previously proposed new techniques to identify parameters of a finite element model, i.e. the density and the modulus of elasticity, of two types of cantilever beam, by using an image processing technique. One beam was a combined beam, the other a damaged beam with a small crack. To identify the parameters of a small segment of the combined beam, spline smoothing with symmetrization and the weighted Tikhonov regularization technique were used. In addition, to detect the size and the location of a small crack, a new type of Simulated Annealing method was proposed.
In this paper, we evaluate our technique experimentally in order to confirm its applicability with a high accuracy to an actual system. Both methods studied are shown to yield highly accurate estimations.
