Abstract
This paper deals with stability analysis of elastic pipeline containing water flow, the velocity of which is perturbed harmonically under an action of pulsate fluid flow. The stability conditions of the pipeline section are analyzed under assumption of the mathematical model of fluid caused by longitudinal force with Poisson characteristics and application of the stochastic modification of the second Lyapunov method.
