SUMMARY

The discussion clarifies the definitions of "clamped" and "simply supported" plates in the context of plate vibration theory. A clamped plate features fixed edges where both edge deflection and edge slopes are zero, akin to beams with fixed ends. In contrast, a simply supported plate allows for edge deflection to be zero while permitting variable slopes based on loading conditions. These distinctions are crucial for understanding the behavior of plates under various loading scenarios.

Hey, I've recently been taking a look at the theory of plate vibration, but I can't seem to find anywhere an exact definition of what consitutes a "clamped" and a "simply supported" plate. What exactly are these, conceptually and mathematically?

I am not sure I have an exact definition, but a plate with "clamped" or "fixed" edges would be welded all around for example. A simple support would be a vertical rest only.
 
The boundary conditions for a clamped plate generally indicate that the edge deflection and edge slopes are both equal to zero (similar boundary conditions are used for beams with fixed ends).

A simply supported plate has edge deflection = 0, but the slope of the plate can vary depending on the loading.
