This paper presents a finite element approach for nonlinear vibration analysis of Timoshenko pipes conveying fluid. An approach using the concept of fictitious loads to account for the kinematic corrections was applied to establish the finite element model, without the need to establish the nonlinea

Based on a novel extended version of the Lagrange equations for systems containing non-material volumes, the nonlinear equations of motion for cantilever pipe systems conveying fluid are deduced. An alternative to existing methods utilizing Newtonian balance equations or Hamilton's principle is thus

In this study, the transverse vibrations of highly tensioned pipes with vanishing #exural sti!ness and conveying #uid with time-dependent velocity are investigated. Two di!erent cases, the pipes with "xed}"xed end and "xed}sliding end conditions are considered. The time-dependent velocity is assumed

The non-linear equations of motion of a #exible pipe conveying unsteadily #owing #uid are derived from the continuity and momentum equations of unsteady #ow. These partial di!erential equations are fully coupled through equilibrium of contact forces, the normal compatibility of velocity at the #uid}
