✦ Synopsis

The vibration transmission characteristics of a flexural incident wave arriving at a rightangled joint with compliance were presented in a previous paper. The case of a longitudinal incident wave arriving at the same joint is the subject of this paper. The study showed that most of the power of the longitudinal incident wave was reflected back as a longitudinal wave at the joint. Flexural waves induced in both members of the joint are generally very low. At high frequencies, however, strong flexural waves will be induced into the second member. The results also show that both transmitted flexural and longitudinal waves can be controlled to some extent by careful design of the stiffness of the joint. Damping at the joint does not offer any advantage in controlling the flexural and longitudinal waves induced by the longitudinal incident wave.
