Non-axisymmetric dynamic response of a buried orthotropic cylindrical shell due to incident shear waves

Abstract

This paper deals with the non-axisymmetric dynamic response of buried orthotropic cylindrical shells excited by shear waves travelling in the surrounding infinite medium. Numerical results have been presented for the cases of incident SV- and SH-waves. For the case of an SV-wave, the flexural and axisymmetric modes have been compared. It has been found that the shell deformations in the flexural mode may be even higher than those in the axisymmetric mode. For SH-waves, only the flexural mode response has been presented as the axisymmetric response does not exist for this case. Shell response for both SV- and SH-waves is found to be significantly influenced by the shell orthotropy parameters, the ground conditions around the shell and the wave speed along the shell axis. © 1988.
