| Abstract: | The propagation behavior of Love waves in layered structures with functionally graded materials is discussed. Two kinds of functions are assumed for the shear modulus along the thickness in the overlying layer. Based on the two hypothesis and the WKB method, the analytic solution of wave propagation problem are obtained. Some results of propagation of Love waves in functionally graded materials layer are obtained and discussed. |
