Abstract. The interfacial mechanical properties between solid bodies in contact can be effectively monitored using ultrasonic guided waves. The contact interface can be effectively modeled as a spring-type interface that has equivalent stiffness in the normal and tangential directions. The influence of the spring stiffnesses constants on the symmetric and antisymmetric modes of propagation is analyzed in the present work.
