Application of the Wavelet Transform and Lipschitz Exponent for the Evaluation of Sandwich Panel Deformations at the Support

The paper presents the application of wavelet transform and Lipschitz exponent for the evaluation of the failure of sandwich panels used in civil engineering. The three-layer panels have a thick and susceptible core that suffers significant deformations in the vicinity of local impacts, for example at a support. To assess the level of failure of the panel, the analysis of its displacements caused by static load was performed. The obtained results confirmed the effectiveness of the method.
