Example 7: Free Surface Wave Breaking Due to High Level of Excitation

A rectangular tank of 10 ft. width, 10 ft. liquid height and 2 inches wall thickness is subjected to a sinusoidal ground excitation given by

$\displaystyle \ddot{G}_x$=$\displaystyle 1.0 g \cos(3.81 t)$ 

Since the level of excitation is relatively high, the liquid is expected to respond violently to the strong high frequency vibrations delivered to the liquid throughout the tank walls. As expected, the free surface wave breaks at time 4.0 seconds, as shown in Fig (4.24).
