  • Experimental verification of an approximate technoque for damage identification in beams using nonlinear regression analysis of bending frequency changes
    Ekinovic, Elma ...
    This paper presents the experimental verification of an approximate technique for damage identification in beam-like structures, which is based on the use of bending frequency changes and nonlinear ... regression analysis. The proposed technique was explained in details in [7] so only few necessary steps are recalled here. The identification of damage location and its depth is performed by use of experimentally measured frequency changes and previously established regression relations between bending frequency changes and damage parameters. The experiments were performed on the intact and damaged beams. The damage in these experiments is made by saw cut as a narrow open notch perpendicular to the beam axis. The results of identification are promising taking into account inevitable modelling and measurement errors.
