FINITE ELEMENT METHOD TO DETERMINE CRITICAL WEIGHT OF FLEXIBLE PIPE CONVEYING FLUID SUBJECTED TO END MOMENTS

摘要

This paper aims to evaluate the critical weight of flexible pipe subjected to applied end moments at fixed support locations. The pipe is hinged at one end, while the other end is free to slide over a frictionless support. The horizontal distance between the two supports is fixed. The model formulation is developed by the variational approach, and the finite element method is employed to obtain the numerical solutions. The critical weights are evaluated for various values of end moments and the proportional parameter of the end moments.
