Non-axisymmetric dynamic response of imperfectly bonded buried orthotropic pipelines

Dwivedi JP, Mishra BK, Upadhyay PC

Abstract

This paper deals with the non-axisymmetric dynamic response of an imperfectly bonded buried orthotropic pipeline subjected to longitudinal wave (P-wave) excitation. An infinite cylindrical shell model, including the rotary inertia and shear deformation effects, has been used for the pipeline. For some cases comparison of axisymmetric and non-axisymmetric responses have also been furnished.

Key Words

orthotropic, axisymmetric, buried, dynamic response, imperfect bond, cylindrical shell
