Abstract

 In this paper, natural frequency and response of FORCED VIBRATION of COMPOSITE LAMINATED CONICAL SHELLs under different boundary conditions are investigated. To this end, equations of Donnell's thin shell theory are used as governing equations. The analytical GALERKIN METHOD together with beam mode shapes as weighting functions is employed to solve the problem. Due to importance of boundary conditions upon the mechanical behavior of CONICAL SHELLs, the analysis is carried out for all possible boundary conditions. The response of FORCED VIBRATION is calculated via the modal participation factor method. Numerical comparisons of FREE VIBRATION with the results in the open literature are made to validate the present methodology.
