SS-V: 2010 In-plane Vibration of a Cantilever Plate

Test No. VM01 Find the fundamental frequency for in-plane vibration of a cantilevered plate.

Definition



Figure 1.

To exclude out-of-plane vibration of the plate, its surface is constrained in the z-direction (Uz = 0).

The units are IPS.

The material properties are:
