Application103 Vibration Analysis of Drumhead

This example analyzes the vibration of a drumhead, which is subjected to varying magnitudes of a tensile force and subsequently hit by a ball.

Analysis Model:
To reduce computation time, a quarter model is analyzed.
In the stress-transient analysis, gradually apply a tensile force to a drumhead, followed by applying a load to a ball, and make the ball strike the drumhead.

The drumhead vibrates with the impact of the ball. The cycle of the vibration depends on the magnitude of the tensile force.
