Abstract
The generalized dispersion equations for guided waves in layered bonding composites with perfect, weak, slip or unbonded interfaces are derived. The effect of the interfacial mechanical properties on the propagation properties of ultrasonic Lamb waves are analyzed by calculating the dispersion curves of the two-layer bonding composites with different bonding conditions. In conjunction with the method of least square, the secant algorithm is used to estimate the interfacial radial and axial elastic coefficients of the layered bonding composite. The reasons for evaluation error of the parameters and the sensitivity of the method for different parameters are analyzed.
