摘要: The purpose of this study is to characterize by ultrasound a bonded structure metal/adhesive/metal. At first, we investigate the guided modes for adhesive layer in its entirety; exact model. Secondly, assume that described one geometrical interface, with superficial distribution longitudinal and transversal springs or without mass; rheological A comparison two models allows determinate validity limits modelling define equivalent stiffness coefficients mass as function frequency. Some cutoff-frequencies are better evaluated when taken into account.
