This report is about response analysis using Statistical Energy Analysis (SEA) with FEM for two panels connected in L-shape. Viscoelastic damping materials are laminated on the panels. One of the panels has a bead formed in circular ring. Usually, modal damping is influenced by shape of panels and forms of the connection. Therefore, to consider coupling in damping between substructures, we proposed calculation method using FEM and MSE (Modal Strain Energy) method to identify internal loss factors. We changed the inner diameter of the circular ring. As a result, we could identify SEA parameters in high precision. And the proposed SEA enables us to improve not only precision in high frequency but also precision in low frequency.
