Precision Element Method for Free Vibration Analysis of Rotational Shells with Partial Viscoelastic Core

Abstract:

Based on the elastic thin shell and layer wise theories, the first order differential matrix equation of a PCLD rotational shell is formulated. According to the principles of the finite element method and precision integration technology, a semi-analytical method, named precision element method, for the free vibration characteristic of a PCLD rotational shell is developed. Numerical results show that the present method is accurate and efficient.
