Modelling Bending Wave Transmission across Coupled Plate Systems Comprising Periodic Ribbed Plates in the Low-, Mid-, and High-Frequency Ranges Using Forms of Statistical Energy Analysis

Figure 8

L-junction B. Excitation: Plate 2. Energy level differences between the periodic ribbed plate (Plate 2) and each of the bays that form the other periodic ribbed plate (Plate 1). Comparison between FEM and ASEA (FEM data are shown using markers with continuous lines; ASEA data are shown using markers with dotted lines). Upper -axis indicates the mode counts for each bay of the ribbed plates ( and ).
