MOVAHEDIAN, Bashir  e  BOTSHEKAN, Meshkat. An Analytical Time Domain Solution for the Forced Vibration Analysis of Thick-Walled Cylinders. Lat. Am. j. solids struct. [online]. 2017, vol.14, n.9, pp.1741-1751. ISSN 1679-7825.  https://doi.org/10.1590/1679-78253549.

In this paper, we propose a time domain analytical solution for the forced vibration analysis of thick-walled hollow cylinders in presence of polar orthotropy. In this regard, solution of the governing equation is decomposed into two parts. The role of the first one is to satisfy boundary conditions utilizing the method of separation of variables besides of Fourier series expansion of the non-homogenous boundary conditions. The second part has been also expressed as the series of orthogonal characteristic functions with the aim of satisfaction of initial conditions. The proposed analytical solution has been implemented to evaluate the dynamic response of the cylinder in solution of some sample problems which are chosen from previous studies.
