| General | 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. |
| Result | The drumhead vibrates with the impact of the ball. The cycle of the vibration depends on the magnitude of the tensile force. Please see Femet Official YouTube Channel where you can see the movie of this example. Click here! |
