Abstract

Based on the classical shell theory of Donnell’s, the application of DQEM about the cylindrical shells steady-state harmonic response was presented. The results show that DQEM is convenient to calculate the response with different boundary conditions. And with the comparison between FEM and DQEM, the latter is oriented to the differential equation of problem, and can obtain the sufficient calculation precision with the less nodes number, the computational efficiency is higher. The results in this article could provide reference for the research about the application of DQEM to the structure dynamic response.
