Application of cubic spline interpolation with optimal spatial sampling for damage identification

L. Pedroso et al.

Summary: This paper introduces a new technique for structural damage identification using cubic spline interpolation, validated through experiments. The differentiation of spline interpolation leads to better damage identifications, and the method performs well in identifying small and multiple damages.

Wavelet-based damage localization and severity estimation of experimental RC beams subjected to gradual static bending tests

Hashem Jahangir et al.

Summary: This study analyzed the modal curvatures of experimental and numerical RC beams using wavelet transform to identify the locations and severities of damages, proposing two damage indices based on wavelet coefficients of modal curvatures at undamaged and damaged states. The second proposed damage index was able to assess the increasing trend of damage in different levels and accurately detect the locations of all damage scenarios in numerical models, as well as successfully detect the damaged degrees of freedoms and corresponding severities in experimental RC beams. The predicted crack propagation trend by the proposed damage indices aligned with experimental observations.

Damage identification by wavelet analysis of modal rotation differences

Andrzej Katunin et al.

Summary: This paper presents a novel damage identification approach based on differences in modal rotation fields obtained from shearographic measurements of structures and post-processed with the 2D continuous wavelet transform-based algorithm. It has been shown that the baseline approach improves the sensitivity of the method to damage, allowing for the identification of smaller damage compared to baseline-free methods. Additionally, a new method for reducing boundary effects and improving visualization of results maps has been introduced.
