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 14

Three coupled plates. Excitation: Plate 3. Energy level differences between the isotropic plate (Plate 3) and each of the bays that form the other periodic ribbed plate (Plate 1) as well as the other isotropic plate (Plate 2). Comparison between FEM and ASEA (FEM data are shown using markers with continuous lines; ASEA data are shown using markers with dotted lines).
