摘要

•Analysis the acoustic scattering of a plane wave from composite cylindrical shells.•Use of the time-frequency representation and plane of modal identification to identify the cutoff frequencies of surface waves.•Three prediction scenarios are assessed.•Compare the performance of ANN, SVM and ANFIS to predict the reduced cutoff frequency of composite structures.
