Frequency Domain Spectral Element Model for the Vibration Analysis of a Thin Plate with Arbitrary Boundary Conditions

Figure 10

Comparison of the impulse-induced vibration responses at = 0.1 m and 0.2 m on the -axis of a simply supported square plate predicted by the present SEM, the modal analysis method (MAM), and the FEM(n), where n is the number of finite elements used in the analysis.
