A multi-nodal ring finite element for analysis of pipe deflection

View document

Bibliographic Details
Summary:The main objective of this work is to present a numerical formulation to solve the problem of the deformation analysis ot thin-walled circular cylindrical pipes under concentred loads. The solutions is based on a displacement field entirely defined from a set of trigonometic functiobns where the amplitudes are assigned as a nodal paramenters in a multi-nodal finite element. With this formulation it is possible to provide an easy alternative tool when compared with a complex finite shell or solid element modelling for the same type of applications. The present work permits to examine the defection of pipe rings subjected to lateral (transverse) static loading conditions. Several case studies presented have been compared and discussed with numericalç analysisresults obtained with a shell element from Ansys programme.
