Abstract : The report presents the results of a theoretical and experimental study of the flexural-wave-transmission properties of plate joints and rod joints. A discussion of the theory of possible wave-transmitting mechanisms illustrates the complexity of the problem. Finite clamping length is included in a theoretical analysis of the transmission properties of rod joints. Solutions are presented for the transmitted, reflected, and nearfield amplitude terms in dimensionless parameters that refer to the physical characteristics of the joint. It is shown that, at low frequencies, joint rotation is the dominant mechanism of transmission; whereas, at the higher frequencies, centroid displacement dominates. Qualitative experimental agreement for this theory is included. (Author)
