Has anyone had any experience with or can direct me to detailed literature on how to determine theoretic natural frequencies of a composite cylinder with a non-symmetric layup? I am trying to obtain these for use in a Bayesian estimation to determine elastic constants of the material through natural frequency measurements.
Dear Michael
This is a straight forward calculation. The composites functionality in the Strand7 (Google this) FEA code does this routinely for any for any form of layup.

Thank you for your response, I will look into your recommendation. However, I was looking to develop an algorithm that would iteratively determine natural frequencies based on varying trial values of mechanical properties rather than using an external software package.
Thanks again,
Michael Pinto
Amin,
I have measured the natural frequencies experimentally using a modal test (impact hammer). Now I would like to compare these with theoretic values of the natural frequencies based on the material properties so that I can create better estimated of the elastic constants of my material.
