Following the Rayleigh-Ritz procedure, we substitute for \(w\)
using equation 5 in equation 4, carry out the double integrations,
and differentiate with respect to each of the \(c_i\)
in turn. Setting the derivatives equal to zero then results in a set
of algebraic equations for the \(c_i\):
| (Eqn. 8) |
The components of the
matrices \(\mathbf{A}\) and \(\mathbf{B}\)
are functions of \(\lambda\)
(which depends on the frequency, tension and area density)
and of the vertex coördinates of the triangular
element.
