| contents | Matrix damage detection in laminated composite structures by Discrete Wavelet Transform Albert Willian Faria Rodrigo Alves e Silva Edson Hideki Koroishi Ingeniería FSDT Wavelet analysis Finite Element Method cracked composite plates The present paper seeks to enhance the potential damage detention and location of the discrete wavelet transform (DWT) in a thin laminated composite damaged by a signal derived from vibration modes. The DWT-1D is used to spatially identify (x-y plane) the damage location. The matrix damage level occurs during the impulsive load application over the analyzed structure. The finite element used is a Serendipity-type element with a rectangular shape, eight nodes and five mechanical degrees-of-freedom per node, and is formulated by First-order shear Deformation Theory (FSDT). The dynamic equation of motion including internal damage is solved by the Newmark implicit integration method, considering small deformations. The results have demonstrated that discrete mother wavelets applied in dynamic modal signal processing are capable of detecting a small damage magnitude in the matrix level. The wavelet coefficients reached great amplitudes in the damaged area. 2019 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303260200046 https://www.redalyc.org/journal/3032/303260200046/ https://www.redalyc.org/journal/3032/303260200046/html/ https://www.redalyc.org/journal/3032/303260200046/303260200046.epub https://www.redalyc.org/journal/3032/303260200046/movil https://doi.org/10.4025/actascitechnol.v41i1.39046 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
