Inverse Identification of Elastic Constants of Orthotropic Plates Using the Dispersion of Guided Waves and Artifical Neural Network

摘要：

　　Using guided wave dispersion characteristics,a procedure based on artificial neural network (ANN) is presented to inversely determine the elastic constants of orthotropic plate.The Legendre polynomial method is employed as the forward solver to calculate the dispersion curves of SH wave for orthotropic plates.The group velocities of lowest modes at five lower frequencies are used as the inputs for the ANN model.The outputs of the ANN are the elastic constants of orthotropic plates.This procedure is examined for an actual orthotropic plate.The results indicate that the identified elastic constants are sufficiently close to the original one.The developed inverse procedure is concluded to be robust and efficient.
