# Plate Deflection Amplitude

## Plate Deflection Amplitude

(OP)
Hello,

I would like to apply Rayleigh-Ritz Method of Minimum Energy to calculate the deflection amplitude and thus the deflection function.

Given the boundary conditions of a clamped-free-clamped-free plate the admissible functions chosen result in a deflection formula as follows:

w(x,y)=∑(n=1):A*(1-cos(2*π*n*x/a))

How can I calculate A?

Any help would be greatly appreciated.

Sam

### RE: Plate Deflection Amplitude

are you sure this isn't a student post ?

if not, I'm sure worked examples should show you what to do. It looks to me as though A is the maximum deflection.
