Vibration Analysis of Thin Plate Structures Subjected to a Moving Force Using Frequency-Domain Spectral Element Method

Figure 12

Comparison of the vibration responses obtained by the integral transform method (ITM) [5], FEM [14], and SEM at the center of the S-S-S-S square plate (Example 1) subjected to a moving point force whose trajectory is given by Case 1 of (39), where  = 5 m/s. (a) ITM [5] versus SEM. (b) FEM [14] versus SEM.
